commit 8355b2b59221c58b33d686a0a2b4f22a19a3c330
Author: Stefano Lattarini <address@hidden>

test defs: new functions to analyze configure help screen
* tests/defs (extract_configure_help, grep_configure_help): New
functions.
* tests/maintmode-configure-msg.test: Use them, reducing code
duplication and test brittleness.
* tests/help-depend.test: Likewise.
* tests/help-depend2.test: Likewise.
* tests/help-dmalloc.test: Likewise.
* tests/help-lispdir.test: Likewise.
* tests/help-multilib.test: Likewise.
* tests/help-python.test: Likewise.
* tests/help-regex.test: Likewise.
* tests/help-silent.test: Likewise.
* tests/help-upc.test: Likewise.
* tests/help-init.test: Make grepping of configure help screen
slightly stricter.
* tests/self-check-configure-help.test: New self test.
* tests/Makefile.am (TESTS): Add it.
From a report by Jim Meyering.

+`configure' configures GNU coreutils 8.14a to adapt to many kinds of systems.
+
+Usage: ./configure [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print `checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for `--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or `..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [/usr/local]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, `make install' will install all the files in
+`/usr/local/bin', `/usr/local/lib' etc. You can specify
+an installation prefix other than `/usr/local' using `--prefix',
+for instance `--prefix=$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
+ --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
+ --localstatedir=DIR modifiable single-machine data [PREFIX/var]
+ --libdir=DIR object code libraries [EPREFIX/lib]
+ --includedir=DIR C header files [PREFIX/include]
+ --oldincludedir=DIR C header files for non-gcc [/usr/include]
+ --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
+ --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
+ --infodir=DIR info documentation [DATAROOTDIR/info]
+ --localedir=DIR locale-dependent data [DATAROOTDIR/locale]
+ --mandir=DIR man documentation [DATAROOTDIR/man]
+ --docdir=DIR documentation root [DATAROOTDIR/doc/coreutils]
+ --htmldir=DIR html documentation [DOCDIR]
+ --dvidir=DIR dvi documentation [DOCDIR]
+ --pdfdir=DIR pdf documentation [DOCDIR]
+ --psdir=DIR ps documentation [DOCDIR]
+
+Program names:
+ --program-prefix=PREFIX prepend PREFIX to installed program names
+ --program-suffix=SUFFIX append SUFFIX to installed program names
+ --program-transform-name=PROGRAM run sed PROGRAM on installed program names
+
+System types:
+ --build=BUILD configure for building on BUILD [guessed]
+ --host=HOST cross-compile to build programs to run on HOST [BUILD]
+
+Optional Features:
+ --disable-option-checking ignore unrecognized --enable/--with options
+ --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
+ --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
+ --enable-silent-rules less verbose build output (undo: `make V=1')
+ --disable-silent-rules verbose build output (undo: `make V=0')
+ --disable-dependency-tracking speeds up one-time build
+ --enable-dependency-tracking do not reject slow dependency extractors
+ --disable-largefile omit support for large files
+ --enable-threads={posix|solaris|pth|win32}
+ specify multithreading API
+ --disable-threads build without multithread safety
+ --disable-acl do not support ACLs
+ --disable-assert turn off assertions
+ --disable-rpath do not hardcode runtime library paths
+ --disable-xattr do not support extended attributes
+ --disable-libcap disable libcap support
+ --enable-gcc-warnings turn on lots of GCC warnings (for developers)
+ --enable-install-program=PROG_LIST
+ install the programs in PROG_LIST (comma-separated,
+ default: none)
+ --enable-no-install-program=PROG_LIST
+ do NOT install the programs in PROG_LIST
+ (comma-separated, default: arch,hostname,su)
+ --disable-nls do not use Native Language Support
+
+Optional Packages:
+ --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
+ --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
+ --with-gnu-ld assume the C compiler uses GNU ld default=no
+ --with-libiconv-prefix[=DIR] search for libiconv in DIR/include and DIR/lib
+ --without-libiconv-prefix don't search for libiconv in includedir and
libdir
+ --with-libpth-prefix[=DIR] search for libpth in DIR/include and DIR/lib
+ --without-libpth-prefix don't search for libpth in includedir and libdir
+ --without-included-regex
+ don't compile regex; this is the default on systems
+ with recent-enough versions of the GNU C Library
+ (use with caution on other systems).
+ --without-selinux do not use SELinux, even on systems with SELinux
+ --with-packager String identifying the packager of this software
+ --with-packager-version Packager-specific version information
+ --with-packager-bug-reports
+ Packager info for bug reports (URL/e-mail/...)
+ --with-tty-group[=NAME]
+ group used by system for TTYs, "tty" when not
+ specified (default: do not rely on any group used
+ for TTYs)
+ --without-gmp do not use the GNU MP library for arbitrary
+ precision calculation (default: use it if available)
+ --with-libintl-prefix[=DIR] search for libintl in DIR/include and DIR/lib
+ --without-libintl-prefix don't search for libintl in includedir and
libdir
+
+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ CPP C preprocessor
+ YACC The `Yet Another C Compiler' implementation to use. Defaults to
+ `bison -y'. Values other than `bison -y' will most likely break
+ on most systems.
+ YFLAGS YFLAGS contains the list arguments that will be passed by
+ default to Bison. This script will default YFLAGS to the empty
+ string to avoid a default value of `-d' given by some make
+ applications.
+ DEFAULT_POSIX2_VERSION
+ POSIX version to default to; see 'config.hin'.
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.
+
+Report bugs to <address@hidden>.
