For those who wonder what's happening currently, we are waiting for
someone at subversions to move some CVS files to install the new
package layout, modeled after the installation tree.
This patch and the following ones are adjusting this change, and move
more and more to autom4te.
Tim, I just realized I did something stupid: lib/Autoconf and
lib/autoconf :( I will change this into lib/Autom4te and
lib/autoconf, don't worry.

- Here is a matrix of mmap possibilities:
- mmap private not fixed
- mmap private fixed at somewhere currently unmapped
- mmap private fixed at somewhere already mapped
- mmap shared not fixed
- mmap shared fixed at somewhere currently unmapped
- mmap shared fixed at somewhere already mapped
- For private mappings, we should verify that changes cannot be read()
- back from the file, nor mmap's back from the file at a different
- address. (There have been systems where private was not correctly
- implemented like the infamous i386 svr4.0, and systems where the
- VM page cache was not coherent with the file system buffer cache
- like early versions of FreeBSD and possibly contemporary NetBSD.)
- For shared mappings, we should conversely verify that changes get
- propogated back to all the places they're supposed to be.
-
- Grep wants private fixed already mapped.
- The main things grep needs to know about mmap are:
- * does it exist and is it safe to write into the mmap'd area
- * how to use it (BSD variants) */

-#

-# If the LHS extends past column 24, then the LHS is terminated with a

-# This section handles about all the preparation aspects for
-# `config.status': registering the configuration files, the headers,
-# the links, and the commands `config.status' will run. There is a
-# little mixture though of things actually handled by `configure',
-# such as running the `configure' in the sub directories. Minor
-# detail.
-#
-# There are two kinds of commands:
-#
-# COMMANDS:
-#
-# They are output into `config.status' via a quoted here doc. These
-# commands are always associated to a tag which the user can use to
-# tell `config.status' what are the commands she wants to run.
-#
-# INIT-CMDS:
-#
-# They are output via an *unquoted* here-doc. As a consequence $var
-# will be output as the value of VAR. This is typically used by
-# `configure' to give `config,.status' some variables it needs to run
-# the COMMANDS. At the difference of `COMMANDS', the INIT-CMDS are
-# always run.
-#
-#
-# Some uniformity exists around here, please respect it!
-#
-# A macro named AC_CONFIG_FOOS has three args: the `TAG...' (or
-# `FILE...' when it applies), the `COMMANDS' and the `INIT-CMDS'. It
-# first checks that TAG was not registered elsewhere thanks to
-# AC_CONFIG_UNIQUE. Then it registers `TAG...' in AC_LIST_FOOS, and for
-# each `TAG', a special line in AC_LIST_FOOS_COMMANDS which is used in
-# `config.status' like this:
-#
-# case $ac_tag in
-# AC_LIST_FOOS_COMMANDS
-# esac
-#
-# Finally, the `INIT-CMDS' are dumped into a special diversion, via
-# `_AC_CONFIG_COMMANDS_INIT'. While `COMMANDS' are output once per TAG,
-# `INIT-CMDS' are dumped only once per call to AC_CONFIG_FOOS.
-#
-# It also leave the TAG in the shell variable ac_config_foo which contains
-# those which will actually be executed. In other words:
-#
-# if false; then
-# AC_CONFIG_FOOS(bar, [touch bar])
-# fi
-#
-# will not create bar.
-#
-# AC_CONFIG_FOOS can be called several times (with different TAGs of
-# course).
-#
-# Because these macros should not output anything, there should be `dnl'
-# everywhere. A pain my friend, a pain. So instead in each macro we
-# divert(-1) and restore the diversion at the end.
-#
-#
-# Honorable members of this family are AC_CONFIG_FILES,
-# AC_CONFIG_HEADERS, AC_CONFIG_LINKS and AC_CONFIG_COMMANDS. Bad boys
-# are AC_LINK_FILES, AC_OUTPUT_COMMANDS and AC_OUTPUT when used with
-# arguments. False members are AC_CONFIG_SRCDIR, AC_CONFIG_SUBDIRS

-# LIST is an AC_CONFIG list, i.e., a list of DEST[:SOURCE], separated

-#
-# FIXME: This macro is badly designed, but I'm not guilty: m4 is. There

-#
-# This is a subroutine of _AC_OUTPUT_CONFIG_STATUS. It has to send
-# itself into $CONFIG_STATUS (eg, via here documents). Upon exit, no
-# here document shall be opened.
-#
-#
-# The code produced used to be extremely costly: there are was a
-# single sed script (n lines) handling both `#define' templates,
-# `#undef' templates with trailing space, and `#undef' templates
-# without trailing spaces. The full script was run on each of the m
-# lines of `config.h.in', i.e., about n x m.
-#
-# Now there are two scripts: `conftest.defines' for the `#define'
-# templates, and `conftest.undef' for the `#undef' templates.
-#
-# Optimization 1. It is incredibly costly to run two `#undef'
-# scripts, so just remove trailing spaces first. Removes about a
-# third of the cost.
-#
-# Optimization 2. Since `#define' are rare and obsoleted,
-# `conftest.defines' is built and run only if grep says there are
-# `#define'. Improves by at least a factor 2, since in addition we
-# avoid the cost of *producing* the sed script.
-#
-# Optimization 3. In each script, first check that the current input
-# line is a template. This avoids running the full sed script on
-# empty lines and comments (divides the cost by about 3 since each
-# template chunk is typically a comment, a template, an empty line).
-#
-# Optimization 4. Once a substitution performed, since there can be
-# only one per line, immediately restart the script on the next input
-# line (using the `t' sed instruction). Divides by about 2.
-# *Note:* In the case of the AC_SUBST sed script (_AC_OUTPUT_FILES)
-# this optimization cannot be applied as is, because there can be
-# several substitutions per line.

-# compiler should pass to the linker (LINKER-OPTIONS) and the name of
-# a shell variable (SHELL-VARIABLE). The list of linker options are
-# appended to the shell variable in a compiler-dependent way.
-#
-# For example, if the selected language is C, then this:
-#

-#
-# will expand into this if the selected C compiler is gcc:

-#
-# otherwise, it will expand into this:

-# AC_F77_LIBRARY_LDFLAGS
-# ----------------------
-#
-# Determine the linker flags (e.g. "-L" and "-l") for the Fortran 77
-# intrinsic and run-time libraries that are required to successfully
-# link a Fortran 77 program or shared library. The output variable
-# FLIBS is set to these flags.
-#
-# This macro is intended to be used in those situations when it is
-# necessary to mix, e.g. C++ and Fortran 77, source code into a single
-# program or shared library.
-#
-# For example, if object files from a C++ and Fortran 77 compiler must
-# be linked together, then the C++ compiler/linker must be used for
-# linking (since special C++-ish things need to happen at link time
-# like calling global constructors, instantiating templates, enabling
-# exception support, etc.).
-#
-# However, the Fortran 77 intrinsic and run-time libraries must be
-# linked in as well, but the C++ compiler/linker doesn't know how to
-# add these Fortran 77 libraries. Hence, the macro
-# "AC_F77_LIBRARY_LDFLAGS" was created to determine these Fortran 77
-# libraries.
-#
-# This macro was packaged in its current form by Matthew D. Langston.
-# However, nearly all of this macro came from the "OCTAVE_FLIBS" macro
-# in "octave-2.0.13/aclocal.m4", and full credit should go to John
-# W. Eaton for writing this extremely useful macro. Thank you John.

-#
-# Detect name of dummy main routine required by the Fortran libraries,
-# (if any) and define F77_DUMMY_MAIN to this name (which should be
-# used for a dummy declaration, if it is defined). On some systems,
-# linking a C program to the Fortran library does not work unless you
-# supply a dummy function called something like MAIN__.
-#
-# Execute ACTION-IF-NOT-FOUND if no way of successfully linking a C
-# program with the F77 libs is found; default to exiting with an error
-# message. Execute ACTION-IF-FOUND if a dummy routine name is needed
-# and found or if it is not needed (default to defining F77_DUMMY_MAIN
-# when needed).
-#
-# What is technically happening is that the Fortran libraries provide
-# their own main() function, which usually initializes Fortran I/O and
-# similar stuff, and then calls MAIN__, which is the entry point of
-# your program. Usually, a C program will override this with its own
-# main() routine, but the linker sometimes complain if you don't
-# provide a dummy (never-called) MAIN__ routine anyway.
-#
-# Of course, programs that want to allow Fortran subroutines to do
-# I/O, etcetera, should call their main routine MAIN__() (or whatever)
-# instead of main(). A separate autoconf test (AC_F77_MAIN) checks
-# for the routine to use in this case (since the semantics of the test
-# are slightly different). To link to e.g. purely numerical
-# libraries, this is normally not necessary, however, and most C/C++
-# programs are reluctant to turn over so much control to Fortran. =)
-#
-# The name variants we check for are (in order):

-# General checks. #
-# ---------------- #
-
-# Up to 2.13 included, Autoconf used to provide the macro
-#
-# AC_CHECK_TYPE(TYPE, DEFAULT)
-#
-# Since, it provides another version which fits better with the other
-# AC_CHECK_ families:
-#
-# AC_CHECK_TYPE(TYPE,
-# [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND],
-# [INCLUDES])
-#
-# In order to provide backward compatibility, the new scheme is
-# implemented as _AC_CHECK_TYPE_NEW, the old scheme as _AC_CHECK_TYPE_OLD,
-# and AC_CHECK_TYPE branches to one or the other, depending upon its
-# arguments.
-
-
-
-# _AC_CHECK_TYPE_NEW(TYPE,
-# [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND],
-# [INCLUDES])
-# ------------------------------------------------------------
-# Check whether the type TYPE is supported by the system, maybe via the
-# the provided includes. This macro implements the former task of
-# AC_CHECK_TYPE, with one big difference though: AC_CHECK_TYPE was
-# grepping in the headers, which, BTW, led to many problems until
-# the egrep expression was correct and did not given false positives.
-# It turned out there are even portability issues with egrep...
-#
-# The most obvious way to check for a TYPE is just to compile a variable
-# definition:
-#
-# TYPE my_var;
-#
-# Unfortunately this does not work for const qualified types in C++,
-# where you need an initializer. So you think of
-#
-# TYPE my_var = (TYPE) 0;
-#
-# Unfortunately, again, this is not valid for some C++ classes.
-#
-# Then you look for another scheme. For instance you think of declaring
-# a function which uses a parameter of type TYPE:
-#
-# int foo (TYPE param);
-#
-# but of course you soon realize this does not make it with K&R
-# compilers. And by no ways you want to
-#
-# int foo (param)
-# TYPE param
-# { ; }
-#
-# since this time it's C++ who is not happy.
-#
-# Don't even think of the return type of a function, since K&R cries
-# there too. So you start thinking of declaring a *pointer* to this TYPE:
-#
-# TYPE *p;
-#
-# but you know fairly well that this is legal in C for aggregates which
-# are unknown (TYPE = struct does-not-exist).
-#
-# Then you think of using sizeof to make sure the TYPE is really
-# defined:
-#
-# sizeof (TYPE);
-#
-# But this succeeds if TYPE is a variable: you get the size of the
-# variable's type!!!
-#
-# This time you tell yourself the last two options *together* will make
-# it. And indeed this is the solution invented by Alexandre Oliva.
-#
-# Also note that we use
-#
-# if (sizeof (TYPE))
-#
-# to `read' sizeof (to avoid warnings), while not depending on its type
-# (not necessarily size_t etc.). Equally, instead of defining an unused
-# variable, we just use a cast to avoid warnings from the compiler.
-# Suggested by Paul Eggert.

+# will be output as the value of VAR. This is typically used by
+# `configure' to give `config,.status' some variables it needs to run
+# the COMMANDS. At the difference of `COMMANDS', the INIT-CMDS are
+# always run.
+#
+#
+# Some uniformity exists around here, please respect it!
+#
+# A macro named AC_CONFIG_FOOS has three args: the `TAG...' (or
+# `FILE...' when it applies), the `COMMANDS' and the `INIT-CMDS'. It
+# first checks that TAG was not registered elsewhere thanks to
+# AC_CONFIG_UNIQUE. Then it registers `TAG...' in AC_LIST_FOOS, and for
+# each `TAG', a special line in AC_LIST_FOOS_COMMANDS which is used in
+# `config.status' like this:
+#
+# case $ac_tag in
+# AC_LIST_FOOS_COMMANDS
+# esac
+#
+# Finally, the `INIT-CMDS' are dumped into a special diversion, via
+# `_AC_CONFIG_COMMANDS_INIT'. While `COMMANDS' are output once per TAG,
+# `INIT-CMDS' are dumped only once per call to AC_CONFIG_FOOS.
+#
+# It also leave the TAG in the shell variable ac_config_foo which contains
+# those which will actually be executed. In other words:
+#
+# if false; then
+# AC_CONFIG_FOOS(bar, [touch bar])
+# fi
+#
+# will not create bar.
+#
+# AC_CONFIG_FOOS can be called several times (with different TAGs of
+# course).
+#
+# Because these macros should not output anything, there should be `dnl'
+# everywhere. A pain my friend, a pain. So instead in each macro we
+# divert(-1) and restore the diversion at the end.

+#
+# The code produced used to be extremely costly: there are was a
+# single sed script (n lines) handling both `#define' templates,
+# `#undef' templates with trailing space, and `#undef' templates
+# without trailing spaces. The full script was run on each of the m
+# lines of `config.h.in', i.e., about n x m.
+#
+# Now there are two scripts: `conftest.defines' for the `#define'
+# templates, and `conftest.undef' for the `#undef' templates.
+#
+# Optimization 1. It is incredibly costly to run two `#undef'
+# scripts, so just remove trailing spaces first. Removes about a
+# third of the cost.
+#
+# Optimization 2. Since `#define' are rare and obsoleted,
+# `conftest.defines' is built and run only if grep says there are
+# `#define'. Improves by at least a factor 2, since in addition we
+# avoid the cost of *producing* the sed script.
+#
+# Optimization 3. In each script, first check that the current input
+# line is a template. This avoids running the full sed script on
+# empty lines and comments (divides the cost by about 3 since each
+# template chunk is typically a comment, a template, an empty line).
+#
+# Optimization 4. Once a substitution performed, since there can be
+# only one per line, immediately restart the script on the next input
+# line (using the `t' sed instruction). Divides by about 2.
+# *Note:* In the case of the AC_SUBST sed script (_AC_OUTPUT_FILES)
+# this optimization cannot be applied as is, because there can be

+# It is believed that under HP-UX `fort77' is the name of the native
+# compiler. On some Cray systems, fort77 is a native compiler.
+# cf77 and cft77 are (older) Cray F77 compilers.
+# frt is the Fujitsu F77 compiler.
+# pgf77 and pgf90 are the Portland Group F77 and F90 compilers.
+# xlf/xlf90/xlf95 are IBM (AIX) F77/F90/F95 compilers.
+# lf95 is the Lahey-Fujitsu compiler.

+# Detect name of dummy main routine required by the Fortran libraries,

+# supply a dummy function called something like MAIN__.
+#
+# Execute ACTION-IF-NOT-FOUND if no way of successfully linking a C
+# program with the F77 libs is found; default to exiting with an error
+# message. Execute ACTION-IF-FOUND if a dummy routine name is needed
+# and found or if it is not needed (default to defining F77_DUMMY_MAIN
+# when needed).
+#
+# What is technically happening is that the Fortran libraries provide
+# their own main() function, which usually initializes Fortran I/O and
+# similar stuff, and then calls MAIN__, which is the entry point of
+# your program. Usually, a C program will override this with its own
+# main() routine, but the linker sometimes complain if you don't
+# provide a dummy (never-called) MAIN__ routine anyway.
+#
+# Of course, programs that want to allow Fortran subroutines to do
+# I/O, etcetera, should call their main routine MAIN__() (or whatever)
+# instead of main(). A separate autoconf test (AC_F77_MAIN) checks
+# for the routine to use in this case (since the semantics of the test
+# are slightly different). To link to e.g. purely numerical
+# libraries, this is normally not necessary, however, and most C/C++

+## Type existence. ##

+
+# ---------------- #
+# General checks. #
+# ---------------- #
+
+# Up to 2.13 included, Autoconf used to provide the macro
+#
+# AC_CHECK_TYPE(TYPE, DEFAULT)
+#
+# Since, it provides another version which fits better with the other
+# AC_CHECK_ families:
+#
+# AC_CHECK_TYPE(TYPE,
+# [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND],
+# [INCLUDES])
+#
+# In order to provide backward compatibility, the new scheme is
+# implemented as _AC_CHECK_TYPE_NEW, the old scheme as _AC_CHECK_TYPE_OLD,
+# and AC_CHECK_TYPE branches to one or the other, depending upon its
+# arguments.
+
+
+
+# _AC_CHECK_TYPE_NEW(TYPE,
+# [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND],
+# [INCLUDES])
+# ------------------------------------------------------------
+# Check whether the type TYPE is supported by the system, maybe via the
+# the provided includes. This macro implements the former task of
+# AC_CHECK_TYPE, with one big difference though: AC_CHECK_TYPE was
+# grepping in the headers, which, BTW, led to many problems until
+# the egrep expression was correct and did not given false positives.
+# It turned out there are even portability issues with egrep...
+#
+# The most obvious way to check for a TYPE is just to compile a variable
+# definition:
+#
+# TYPE my_var;
+#
+# Unfortunately this does not work for const qualified types in C++,
+# where you need an initializer. So you think of
+#
+# TYPE my_var = (TYPE) 0;
+#
+# Unfortunately, again, this is not valid for some C++ classes.
+#
+# Then you look for another scheme. For instance you think of declaring
+# a function which uses a parameter of type TYPE:
+#
+# int foo (TYPE param);
+#
+# but of course you soon realize this does not make it with K&R
+# compilers. And by no ways you want to
+#
+# int foo (param)
+# TYPE param
+# { ; }
+#
+# since this time it's C++ who is not happy.
+#
+# Don't even think of the return type of a function, since K&R cries
+# there too. So you start thinking of declaring a *pointer* to this TYPE:
+#
+# TYPE *p;
+#
+# but you know fairly well that this is legal in C for aggregates which
+# are unknown (TYPE = struct does-not-exist).
+#
+# Then you think of using sizeof to make sure the TYPE is really
+# defined:
+#
+# sizeof (TYPE);
+#
+# But this succeeds if TYPE is a variable: you get the size of the
+# variable's type!!!
+#
+# This time you tell yourself the last two options *together* will make
+# it. And indeed this is the solution invented by Alexandre Oliva.
+#
+# Also note that we use
+#
+# if (sizeof (TYPE))
+#
+# to `read' sizeof (to avoid warnings), while not depending on its type
+# (not necessarily size_t etc.). Equally, instead of defining an unused
+# variable, we just use a cast to avoid warnings from the compiler.
+# Suggested by Paul Eggert.

+# STDERR contents.
+#
+# STATUS, STDOUT, and STDERR are not checked if equal to `ignore'.
+#
+# If STDOUT is `expout', then stdout is compared to the content of the file
+# `expout'. Likewise for STDERR and `experr'.
+#
+# If STDOUT is `stdout', then the stdout is left in the file `stdout',
+# likewise for STDERR and `stderr'. Don't do this:
+#
+# AT_CHECK([command >out])
+# # Some checks on `out'
+#
+# do this instead:
+#
+# AT_CHECK([command], [], [stdout])
+# # Some checks on `stdout'
+#
+# This is an unfortunate limitation inherited from Ultrix which will not
+# let you redirect several times the same FD (see the Autoconf documentation).
+# If you use the `AT_CHECK([command >out])' be sure to have the test
+# suite introduces spurious failures.
+#
+# You might wander why not just use `ignore' and directly use stdout and
+# stderr left by the test suite. Firstly because the names of these files
+# is an internal detail, and secondly, because
+#
+# AT_CHECK([command], [], [ignore])
+# AT_CHECK([check stdout])
+#
+# will use `stdout' both in input and output: undefined behavior would
+# certainly result. That's why the test suite will save them in `at-stdout'
+# and `at-stderr', and will provide you with `stdout' and `stderr'.
+#
+# Any line of stderr starting with leading blanks and a `+' are filtered
+# out, since most shells when tracing include subshell traces in stderr.
+# This may cause spurious failures when the test suite is run with `-x'.
+#
+#
+# Implementation Details
+# ----------------------
+# Ideally, we would like to run
+#
+# ( $at_traceon; COMMANDS >at-stdout 2> at-stderr )
+#
+# but we must group COMMANDS as it is not limited to a single command, and
+# then the shells will save the traces in at-stderr. So we have to filter
+# them out when checking stderr, and we must send them into the test suite's
+# stderr to honor -x properly.
+#
+# Limiting COMMANDS to a single command is not good either, since them
+# the user herself would use {} or (), and then we face the same problem.
+#
+# But then, there is no point in running
+#
+# ( $at_traceon { $1 ; } >at-stdout 2>at-stder1 )

+# => echo 1
+# => echo (2,3)
+#
+# which is not what is expected.
+#
+# Of course the problem is that many quotes are missing. So you add

+# reach the following implementation (but if you really did, then

+# => echo a
+# => echo (b
+# => echo c)
+#
+# Bingo!
+#
+# Well, not quite.
+#
+# With a better look, you realize that the parens are more a pain than

+# with always using an outermost pair of parens and an outermost pair
+# of quotes. Rejecting the parens both eases the implementation, and

+## 8. Defining macros with bells and whistles. ##
+## -------------------------------------------- ##
+
+# `m4_defun' is basically `m4_define' but it equips the macro with the
+# needed machinery for `m4_require'. A macro must be m4_defun'd if
+# either it is m4_require'd, or it m4_require's.
+#
+# Two things deserve attention and are detailed below:
+# 1. Implementation of m4_require
+# 2. Keeping track of the expansion stack
+#
+# 1. Implementation of m4_require
+# ===============================
+#
+# Of course m4_defun AC_PROVIDE's the macro, so that a macro which has
+# been expanded is not expanded again when m4_require'd, but the
+# difficult part is the proper expansion of macros when they are
+# m4_require'd.
+#
+# The implementation is based on two ideas, (i) using diversions to
+# prepare the expansion of the macro and its dependencies (by François
+# Pinard), and (ii) expand the most recently m4_require'd macros _after_
+# the previous macros (by Axel Thimm).
+#
+#
+# The first idea: why using diversions?
+# -------------------------------------
+#
+# When a macro requires another, the other macro is expanded in new
+# diversion, GROW. When the outer macro is fully expanded, we first
+# undivert the most nested diversions (GROW - 1...), and finally
+# undivert GROW. To understand why we need several diversions,
+# consider the following example:
+#
+# | m4_defun([TEST1], [Test...REQUIRE([TEST2])1])
+# | m4_defun([TEST2], [Test...REQUIRE([TEST3])2])
+# | m4_defun([TEST3], [Test...3])
+#
+# Because m4_require is not required to be first in the outer macros, we
+# must keep the expansions of the various level of m4_require separated.
+# Right before executing the epilogue of TEST1, we have:
+#
+# GROW - 2: Test...3
+# GROW - 1: Test...2
+# GROW: Test...1
+# BODY:
+#
+# Finally the epilogue of TEST1 undiverts GROW - 2, GROW - 1, and
+# GROW into the regular flow, BODY.
+#
+# GROW - 2:
+# GROW - 1:
+# GROW:
+# BODY: Test...3; Test...2; Test...1
+#
+# (The semicolons are here for clarification, but of course are not
+# emitted.) This is what Autoconf 2.0 (I think) to 2.13 (I'm sure)
+# implement.
+#
+#
+# The second idea: first required first out
+# -----------------------------------------
+#
+# The natural implementation of the idea above is buggy and produces
+# very surprising results in some situations. Let's consider the
+# following example to explain the bug:
+#
+# | m4_defun([TEST1], [REQUIRE([TEST2a])REQUIRE([TEST2b])])
+# | m4_defun([TEST2a], [])
+# | m4_defun([TEST2b], [REQUIRE([TEST3])])
+# | m4_defun([TEST3], [REQUIRE([TEST2a])])
+# |
+# | AC_INIT
+# | TEST1
+#
+# The dependencies between the macros are:
+#
+# 3 --- 2b
+# / \ is m4_require'd by
+# / \ left -------------------- right
+# 2a ------------ 1
+#
+# If you strictly apply the rules given in the previous section you get:
+#
+# GROW - 2: TEST3
+# GROW - 1: TEST2a; TEST2b
+# GROW: TEST1
+# BODY:
+#
+# (TEST2a, although required by TEST3 is not expanded in GROW - 3
+# because is has already been expanded before in GROW - 1, so it has
+# been AC_PROVIDE'd, so it is not expanded again) so when you undivert
+# the stack of diversions, you get:
+#
+# GROW - 2:
+# GROW - 1:
+# GROW:
+# BODY: TEST3; TEST2a; TEST2b; TEST1
+#
+# i.e., TEST2a is expanded after TEST3 although the latter required the
+# former.
+#
+# Starting from 2.50, uses an implementation provided by Axel Thimm.
+# The idea is simple: the order in which macros are emitted must be the
+# same as the one in which macro are expanded. (The bug above can
+# indeed be described as: a macro has been AC_PROVIDE'd, but it is
+# emitted after: the lack of correlation between emission and expansion
+# order is guilty).
+#
+# How to do that? You keeping the stack of diversions to elaborate the
+# macros, but each time a macro is fully expanded, emit it immediately.
+#
+# In the example above, when TEST2a is expanded, but it's epilogue is
+# not run yet, you have:
+#
+# GROW - 2:
+# GROW - 1: TEST2a
+# GROW: Elaboration of TEST1
+# BODY:
+#
+# The epilogue of TEST2a emits it immediately:
+#
+# GROW - 2:
+# GROW - 1:
+# GROW: Elaboration of TEST1
+# BODY: TEST2a
+#
+# TEST2b then requires TEST3, so right before the epilogue of TEST3, you
+# have:
+#
+# GROW - 2: TEST3
+# GROW - 1: Elaboration of TEST2b
+# GROW: Elaboration of TEST1
+# BODY: TEST2a
+#
+# The epilogue of TEST3 emits it:
+#
+# GROW - 2:
+# GROW - 1: Elaboration of TEST2b
+# GROW: Elaboration of TEST1
+# BODY: TEST2a; TEST3
+#
+# TEST2b is now completely expanded, and emitted:
+#
+# GROW - 2:
+# GROW - 1:
+# GROW: Elaboration of TEST1
+# BODY: TEST2a; TEST3; TEST2b
+#
+# and finally, TEST1 is finished and emitted:
+#
+# GROW - 2:
+# GROW - 1:
+# GROW:
+# BODY: TEST2a; TEST3; TEST2b: TEST1
+#
+# The idea, is simple, but the implementation is a bit evolved. If you
+# are like me, you will want to see the actual functioning of this
+# implementation to be convinced. The next section gives the full
+# details.
+#
+#
+# The Axel Thimm implementation at work
+# -------------------------------------
+#
+# We consider the macros above, and this configure.ac:
+#
+# AC_INIT
+# TEST1
+#
+# You should keep the definitions of _m4_defun_pro, _m4_defun_epi, and
+# m4_require at hand to follow the steps.
+#
+# This implements tries not to assume that of the current diversion is
+# BODY, so as soon as a macro (m4_defun'd) is expanded, we first
+# record the current diversion under the name _m4_divert_dump (denoted
+# DUMP below for short). This introduces an important difference with
+# the previous versions of Autoconf: you cannot use m4_require if you
+# were not inside an m4_defun'd macro, and especially, you cannot
+# m4_require directly from the top level.
+#
+# We have not tried to simulate the old behavior (better yet, we
+# diagnose it), because it is too dangerous: a macro m4_require'd from
+# the top level is expanded before the body of `configure', i.e., before
+# any other test was run. I let you imagine the result of requiring
+# AC_STDC_HEADERS for instance, before AC_PROG_CC was actually run....
+#
+# After AC_INIT was run, the current diversion is BODY.

+#
+# 2. Keeping track of the expansion stack
+# =======================================
+#
+# When M4 expansion goes wrong it is often extremely hard to find the
+# path amongst macros that drove to the failure. What is needed is
+# the stack of macro `calls'. One could imagine that GNU M4 would
+# maintain a stack of macro expansions, unfortunately it doesn't, so
+# we do it by hand. This is of course extremely costly, but the help
+# this stack provides is worth it. Nevertheless to limit the
+# performance penalty this is implemented only for m4_defun'd macros,
+# not for define'd macros.
+#
+# The scheme is simplistic: each time we enter an m4_defun'd macros,
+# we prepend its name in m4_expansion_stack, and when we exit the
+# macro, we remove it (thanks to pushdef/popdef).
+#
+# In addition, we want to use the expansion stack to detect circular
+# m4_require dependencies. This means we need to browse the stack to
+# check whether a macro being expanded is m4_require'd. For ease of
+# implementation, and certainly for the benefit of performances, we
+# don't browse the m4_expansion_stack, rather each time we expand a
+# macro FOO we define _m4_expanding(FOO). Then m4_require(BAR) simply
+# needs to check whether _m4_expanding(BAR) is defined to diagnose a
+# circular dependency.
+#
+# To improve the diagnostic, in addition to keeping track of the stack
+# of macro calls, m4_expansion_stack also records the m4_require
+# stack. Note that therefore an m4_defun'd macro being required will
+# appear twice in the stack: the first time because it is required,
+# the second because it is expanded. We can avoid this, but it has
+# two small drawbacks: (i) the implementation is slightly more
+# complex, and (ii) it hides the difference between define'd macros
+# (which don't appear in m4_expansion_stack) and m4_defun'd macros
+# (which do). The more debugging information, the better.

-
-# Sometimes we may have to handle literals (e.g. `stdlib.h'), while at
-# other moments, the same code may have to get the value from a
-# variable (e.g., `ac_header'). To have a uniform handling of both
-# cases, when a new value is about to be processed, declare a local

-# and then in the body of the macro, use `header' as is. It is of
-# first importance to use `AS_VAR_*' to access this variable. Don't
-# quote its name: it must be used right away by m4.
-#
-# If the value `$1' was a literal (e.g. `stdlib.h'), then `header' is
-# in fact the value `ac_cv_header_stdlib_h'. If `$1' was indirect,
-# then `header's value in m4 is in fact `$ac_header', the shell
-# variable that holds all of the magic to get the expansion right.

-# AS_VAR_POPDEF([header])
-
-

-# Implementing `foreach' loops in m4 is much more tricky than it may
-# seem. Actually, the example of a `foreach' loop in the m4
-# documentation is wrong: it does not quote the arguments properly,
-# which leads to undesired expansions.
-#
-# The example in the documentation is:
-#
-# | # foreach(VAR, (LIST), STMT)
-# | m4_define([foreach],
-# | [m4_pushdef([$1])_foreach([$1], [$2], [$3])m4_popdef([$1])])
-# | m4_define([_arg1], [$1])
-# | m4_define([_foreach],
-# | [m4_if([$2], [()], ,
-# | [m4_define([$1], _arg1$2)$3[]_foreach([$1],
-# | (shift$2),
-# | [$3])])])
-#
-# But then if you run
-#
-# | m4_define(a, 1)
-# | m4_define(b, 2)
-# | m4_define(c, 3)
-# | foreach([f], [([a], [(b], [c)])], [echo f
-# | ])
-#
-# it gives
-#
-# => echo 1
-# => echo (2,3)
-#
-# which is not what is expected.
-#
-# Of course the problem is that many quotes are missing. So you add
-# plenty of quotes at random places, until you reach the expected
-# result. Alternatively, if you are a quoting wizard, you directly
-# reach the following implementation (but if you really did, then
-# apply to the maintenance of m4sugar!).
-#
-# | # foreach(VAR, (LIST), STMT)
-# | m4_define([foreach], [m4_pushdef([$1])_foreach($@)m4_popdef([$1])])
-# | m4_define([_arg1], [[$1]])
-# | m4_define([_foreach],
-# | [m4_if($2, [()], ,
-# | [m4_define([$1], [_arg1$2])$3[]_foreach([$1],
-# | [(shift$2)],
-# | [$3])])])
-#
-# which this time answers
-#
-# => echo a
-# => echo (b
-# => echo c)
-#
-# Bingo!
-#
-# Well, not quite.
-#
-# With a better look, you realize that the parens are more a pain than
-# a help: since anyway you need to quote properly the list, you end up
-# with always using an outermost pair of parens and an outermost pair
-# of quotes. Rejecting the parens both eases the implementation, and
-# simplifies the use:
-#
-# | # foreach(VAR, (LIST), STMT)
-# | m4_define([foreach], [m4_pushdef([$1])_foreach($@)m4_popdef([$1])])

-# | [m4_define([$1], [_arg1($2)])$3[]_foreach([$1],
-# | [shift($2)],
-# | [$3])])])
-#
-#
-# Now, just replace the `$2' with `m4_quote($2)' in the outer `m4_if'
-# to improve robustness, and you come up with a quite satisfactory
-# implementation.

-
-# m4_foreach(VARIABLE, LIST, EXPRESSION)

-# to be expanded.
-#

-# `m4_defun' is basically `m4_define' but it equips the macro with the
-# needed machinery for `m4_require'. A macro must be m4_defun'd if
-# either it is m4_require'd, or it m4_require's.
-#
-# Two things deserve attention and are detailed below:
-# 1. Implementation of m4_require
-# 2. Keeping track of the expansion stack
-#
-# 1. Implementation of m4_require
-# ===============================
-#
-# Of course m4_defun AC_PROVIDE's the macro, so that a macro which has
-# been expanded is not expanded again when m4_require'd, but the
-# difficult part is the proper expansion of macros when they are
-# m4_require'd.
-#
-# The implementation is based on two ideas, (i) using diversions to
-# prepare the expansion of the macro and its dependencies (by François
-# Pinard), and (ii) expand the most recently m4_require'd macros _after_
-# the previous macros (by Axel Thimm).
-#
-#
-# The first idea: why using diversions?
-# -------------------------------------
-#
-# When a macro requires another, the other macro is expanded in new
-# diversion, GROW. When the outer macro is fully expanded, we first
-# undivert the most nested diversions (GROW - 1...), and finally
-# undivert GROW. To understand why we need several diversions,
-# consider the following example:
-#
-# | m4_defun([TEST1], [Test...REQUIRE([TEST2])1])
-# | m4_defun([TEST2], [Test...REQUIRE([TEST3])2])
-# | m4_defun([TEST3], [Test...3])
-#
-# Because m4_require is not required to be first in the outer macros, we
-# must keep the expansions of the various level of m4_require separated.
-# Right before executing the epilogue of TEST1, we have:
-#
-# GROW - 2: Test...3
-# GROW - 1: Test...2
-# GROW: Test...1
-# BODY:
-#
-# Finally the epilogue of TEST1 undiverts GROW - 2, GROW - 1, and
-# GROW into the regular flow, BODY.
-#
-# GROW - 2:
-# GROW - 1:
-# GROW:
-# BODY: Test...3; Test...2; Test...1
-#
-# (The semicolons are here for clarification, but of course are not
-# emitted.) This is what Autoconf 2.0 (I think) to 2.13 (I'm sure)
-# implement.
-#
-#
-# The second idea: first required first out
-# -----------------------------------------
-#
-# The natural implementation of the idea above is buggy and produces
-# very surprising results in some situations. Let's consider the
-# following example to explain the bug:
-#
-# | m4_defun([TEST1], [REQUIRE([TEST2a])REQUIRE([TEST2b])])
-# | m4_defun([TEST2a], [])
-# | m4_defun([TEST2b], [REQUIRE([TEST3])])
-# | m4_defun([TEST3], [REQUIRE([TEST2a])])
-# |
-# | AC_INIT
-# | TEST1
-#
-# The dependencies between the macros are:
-#
-# 3 --- 2b
-# / \ is m4_require'd by
-# / \ left -------------------- right
-# 2a ------------ 1
-#
-# If you strictly apply the rules given in the previous section you get:
-#
-# GROW - 2: TEST3
-# GROW - 1: TEST2a; TEST2b
-# GROW: TEST1
-# BODY:
-#
-# (TEST2a, although required by TEST3 is not expanded in GROW - 3
-# because is has already been expanded before in GROW - 1, so it has
-# been AC_PROVIDE'd, so it is not expanded again) so when you undivert
-# the stack of diversions, you get:
-#
-# GROW - 2:
-# GROW - 1:
-# GROW:
-# BODY: TEST3; TEST2a; TEST2b; TEST1
-#
-# i.e., TEST2a is expanded after TEST3 although the latter required the
-# former.
-#
-# Starting from 2.50, uses an implementation provided by Axel Thimm.
-# The idea is simple: the order in which macros are emitted must be the
-# same as the one in which macro are expanded. (The bug above can
-# indeed be described as: a macro has been AC_PROVIDE'd, but it is
-# emitted after: the lack of correlation between emission and expansion
-# order is guilty).
-#
-# How to do that? You keeping the stack of diversions to elaborate the
-# macros, but each time a macro is fully expanded, emit it immediately.
-#
-# In the example above, when TEST2a is expanded, but it's epilogue is
-# not run yet, you have:
-#
-# GROW - 2:
-# GROW - 1: TEST2a
-# GROW: Elaboration of TEST1
-# BODY:
-#
-# The epilogue of TEST2a emits it immediately:
-#
-# GROW - 2:
-# GROW - 1:
-# GROW: Elaboration of TEST1
-# BODY: TEST2a
-#
-# TEST2b then requires TEST3, so right before the epilogue of TEST3, you
-# have:
-#
-# GROW - 2: TEST3
-# GROW - 1: Elaboration of TEST2b
-# GROW: Elaboration of TEST1
-# BODY: TEST2a
-#
-# The epilogue of TEST3 emits it:
-#
-# GROW - 2:
-# GROW - 1: Elaboration of TEST2b
-# GROW: Elaboration of TEST1
-# BODY: TEST2a; TEST3
-#
-# TEST2b is now completely expanded, and emitted:
-#
-# GROW - 2:
-# GROW - 1:
-# GROW: Elaboration of TEST1
-# BODY: TEST2a; TEST3; TEST2b
-#
-# and finally, TEST1 is finished and emitted:
-#
-# GROW - 2:
-# GROW - 1:
-# GROW:
-# BODY: TEST2a; TEST3; TEST2b: TEST1
-#
-# The idea, is simple, but the implementation is a bit evolved. If you
-# are like me, you will want to see the actual functioning of this
-# implementation to be convinced. The next section gives the full
-# details.
-#
-#
-# The Axel Thimm implementation at work
-# -------------------------------------
-#
-# We consider the macros above, and this configure.ac:
-#
-# AC_INIT
-# TEST1
-#
-# You should keep the definitions of _m4_defun_pro, _m4_defun_epi, and
-# m4_require at hand to follow the steps.
-#
-# This implements tries not to assume that of the current diversion is
-# BODY, so as soon as a macro (m4_defun'd) is expanded, we first
-# record the current diversion under the name _m4_divert_dump (denoted
-# DUMP below for short). This introduces an important difference with
-# the previous versions of Autoconf: you cannot use m4_require if you
-# were not inside an m4_defun'd macro, and especially, you cannot
-# m4_require directly from the top level.
-#
-# We have not tried to simulate the old behavior (better yet, we
-# diagnose it), because it is too dangerous: a macro m4_require'd from
-# the top level is expanded before the body of `configure', i.e., before
-# any other test was run. I let you imagine the result of requiring
-# AC_STDC_HEADERS for instance, before AC_PROG_CC was actually run....
-#
-# After AC_INIT was run, the current diversion is BODY.

-# expansion of TEST1 and its dependencies will be elaborated.

-# 2. Keeping track of the expansion stack
-# =======================================
-#
-# When M4 expansion goes wrong it is often extremely hard to find the
-# path amongst macros that drove to the failure. What is needed is
-# the stack of macro `calls'. One could imagine that GNU M4 would
-# maintain a stack of macro expansions, unfortunately it doesn't, so
-# we do it by hand. This is of course extremely costly, but the help
-# this stack provides is worth it. Nevertheless to limit the
-# performance penalty this is implemented only for m4_defun'd macros,
-# not for define'd macros.
-#
-# The scheme is simplistic: each time we enter an m4_defun'd macros,
-# we prepend its name in m4_expansion_stack, and when we exit the
-# macro, we remove it (thanks to pushdef/popdef).
-#
-# In addition, we want to use the expansion stack to detect circular
-# m4_require dependencies. This means we need to browse the stack to
-# check whether a macro being expanded is m4_require'd. For ease of
-# implementation, and certainly for the benefit of performances, we
-# don't browse the m4_expansion_stack, rather each time we expand a
-# macro FOO we define _m4_expanding(FOO). Then m4_require(BAR) simply
-# needs to check whether _m4_expanding(BAR) is defined to diagnose a
-# circular dependency.
-#
-# To improve the diagnostic, in addition to keeping track of the stack
-# of macro calls, m4_expansion_stack also records the m4_require
-# stack. Note that therefore an m4_defun'd macro being required will
-# appear twice in the stack: the first time because it is required,
-# the second because it is expanded. We can avoid this, but it has
-# two small drawbacks: (i) the implementation is slightly more
-# complex, and (ii) it hides the difference between define'd macros
-# (which don't appear in m4_expansion_stack) and m4_defun'd macros
-# (which do). The more debugging information, the better.

-# ------------------------------------------------
-# Execute a test by performing given shell COMMANDS. These commands
-# should normally exit with STATUS, while producing expected STDOUT and
-# STDERR contents.
-#
-# STATUS, STDOUT, and STDERR are not checked if equal to `ignore'.
-#
-# If STDOUT is `expout', then stdout is compared to the content of the file
-# `expout'. Likewise for STDERR and `experr'.
-#
-# If STDOUT is `stdout', then the stdout is left in the file `stdout',
-# likewise for STDERR and `stderr'. Don't do this:
-#
-# AT_CHECK([command >out])
-# # Some checks on `out'
-#
-# do this instead:
-#
-# AT_CHECK([command], [], [stdout])
-# # Some checks on `stdout'
-#
-# This is an unfortunate limitation inherited from Ultrix which will not
-# let you redirect several times the same FD (see the Autoconf documentation).
-# If you use the `AT_CHECK([command >out])' be sure to have the test
-# suite introduces spurious failures.
-#
-# You might wander why not just use `ignore' and directly use stdout and
-# stderr left by the test suite. Firstly because the names of these files
-# is an internal detail, and secondly, because
-#
-# AT_CHECK([command], [], [ignore])
-# AT_CHECK([check stdout])
-#
-# will use `stdout' both in input and output: undefined behavior would
-# certainly result. That's why the test suite will save them in `at-stdout'
-# and `at-stderr', and will provide you with `stdout' and `stderr'.
-#
-# Any line of stderr starting with leading blanks and a `+' are filtered
-# out, since most shells when tracing include subshell traces in stderr.
-# This may cause spurious failures when the test suite is run with `-x'.
-#
-#
-# Implementation Details
-# ----------------------
-# Ideally, we would like to run
-#
-# ( $at_traceon; COMMANDS >at-stdout 2> at-stderr )
-#
-# but we must group COMMANDS as it is not limited to a single command, and
-# then the shells will save the traces in at-stderr. So we have to filter
-# them out when checking stderr, and we must send them into the test suite's
-# stderr to honor -x properly.
-#
-# Limiting COMMANDS to a single command is not good either, since them
-# the user herself would use {} or (), and then we face the same problem.
-#
-# But then, there is no point in running
-#
-# ( $at_traceon { $1 ; } >at-stdout 2>at-stder1 )
-#
-# instead of the simpler
-#
-# ( $at_traceon; $1 ) >at-stdout 2>at-stder1
