FYI: latest "official" cygwin libtool

[Charles Wilson]

I've updated cygwin's libtool packages, using git master
at 2009-02-16 21:59:34 +0100 from git revision
9e9ba5e0e2c0b3f33ee44081c5bc3f0b8991aebd ("Do not pass $INSTALL via
TESTS_ENVIRONMENT."), plus a sequence of patches.

I'm posting these mostly for Peter's benefit, as I included some (but
not all) of his pr-msvc patches -- but had to revise some of them (esp.
add-func_to_tool_path) a bit.  Peter, you might want to look at
07-pr-add-func_to_tool_path.patch and 08-pr-use-LT_AR-...  Also, I found
that 08-pr doesn't work standalone; it requires
09-pr-allow-ms-lib-archiver.patch or you get build errors.

01-fix-dlpreopen-with-disable-static.patch
02-refactor-cwrapper-cross-compile-and-add-cygwin.patch
03-document-and-test-cwrapper-macro.patch
04-pr-dumpbin-link-support.patch
05-pr-lib-prefix-for-archive-name-ltdl.patch
06-pr-preload-heed-libname_spec.patch
07-pr-add-func_to_tool_path.patch
08-pr-use-LT_AR-internally-and-convert-filenames-to-host-format.patch
09-pr-allow-ms-lib-archiver.patch

Note that 01-, 02-, and 03- have already appeared on this list in the
exact form included.  The 0x-pr patches...probably not so much, because
of ripple effects from the first three, but I'll leave that to Peter to
sort out. <g>.

While my build was cygwin native (that is, I didn't exercise much of the
pr-msvc code), it passed all regressions on both cygwin-1.5 and
cygwin-1.7 -- so the pr-patches "do no harm".

I'm going to ask (on the cygwin list) for some test reports by folks who
routinely use unix->cygwin cross environments, so maybe we'll get a
little "in the wild" feedback about
02-refactor-cwrapper-cross-compile-and-add-cygwin.patch.

2008-08-02  Peter Rosin  <...>

        Allow Microsoft lib to be used as the archiver.
        * libltdl/m4/libtool.m4: Add $AR_SEP between $AR_FLAGS and the
        archive file name in all $AR commands.
        (_LT_CMD_OLD_ARCHIVE): Use _LT_PROG_AR to find archiver, not
        AC_CHECK_TOOL.
        * libltdl/config/ltmain.m4sh (func_extract_an_archive): Add support
        for archivers that only supports extracting one member at a time
        and otherwise adjust to the above libtool.m4 changes. Also, add
        $AR_SEP to the $AR invocations.
        * Makefile.am: Pass AR, AR_FLAGS and AR_SEP through to the
        testsuite.
        * tests/archive-in-archive.at: Extract archive name from the .la
        file instead of hardcoding the name, and allow different archivers.

2009-01-26  Peter Rosin  <...>

        Use LT_AR internally and convert archive file to host format
        * libltdl/m4/libtool.m4 (_LT_PROG_AR): Export LT_AR and
        LT_ARFLAGS to the libtool script.
        (_LT_CMD_OLD_ARCHIVE): Make sure they are used.
        * libltdl/config/ltmain.m4sh (func_mode_ar): Convert the
        filename of the archive to host format (MSYS fails to convert
        paths that are prefixed the -out: in arguments).
        Makes stresstest.at go a bit further on MSYS/MSVC.

2009-01-31  Peter Rosin  <...>

        Add func_to_tool_path.
        * libltdl/config/ltmain.m4sh (func_to_tool_path): New function.
        * libltdl/m4/libtool.m4 (_LT_PATH_CONVERSION_FUNCTIONS): Add
        libtool variable $to_tool_path_cmd, and AC_SUBST it.
        * Makefile.am: Ensure to_tool_path_cmd is included in
        TEST_ENVIRONMENT so that it is passed to (old testsuite) tests.
        * tests/testsuite.at: Ensure to_tool_path_cmd is passed as a
        variable setting on the configure line for (new testsuite) tests.

2008-11-24  Peter Rosin  <...>

        Make preloading heed libname_spec.
        * libltdl/ltdl.c (libprefix): New static variable describing
        the prefix of static archives.
        (try_dlopen): Use libprefix.
        * libltdl/m4/ltdl.m4 (_LTDL_SETUP): Export prefix of static
        archives to config.h.

2009-01-26  Peter Rosin  <...>

        Add lib prefix to archive name if needed in symbol list.
        * libltdl/m4/libtool.m4 (_LT_CMD_GLOBAL_SYMBOLS): When lib
        prefix is required, add it - if needed - to the module name as
        well to match what is done to the symbol that is looked up.

2009-01-26  Peter Rosin  <...>

        Don't settle for any dumpbin/link program as name lister.
        * libltdl/m4/libtool.m4 (LT_PATH_NM): When locating dumpbin or
        link -dump, check if they appear to really be capable of name
        listing, in order to eliminate e.g. link from coreutils. This
        makes the name lister decision fall back on nm as the default if
        no acceptable candidate is found.
        * THANKS: Update
        Reports by Rudolf Leitgeb and Peter Kjellerstedt.

2009-02-17  Charles Wilson  <...>

        Document and test LT_DEBUGWRAPPER cwrapper macro
        * tests/cwrapper.test: Add new test for -DLT_DEBUGWRAPPER.
        * doc/libtool.texi [Linking executables]: Mention wrapper
        executables, in addition to wrapper scripts. Add menu referencing
        subsection 'Wrapper executables for programs'.
        [Wrapper executables for programs]: New subsection. Documents
        cwrapper rationale, command line options, and LT_DEBUGWRAPPER
        macro.

2009-02-17  Charles Wilson  <...>

        Refactor cwrapper cross-compile support; Add cygwin.
        * libltdl/m4/libtool.m4 (_LT_PATH_CONVERSION_FUNCTIONS): New
        function sets libtool variable $to_host_path_cmd, and employs
        cache. AC_SUBSTs $to_host_path_cmd, as well.
        (_LT_SETUP): Require it.
        * tests/testsuite.at: Ensure to_host_path_cmd is passed as a
        variable setting on the configure line for (new testsuite) tests.
        * Makefile.am: Ensure to_host_path_cmd is included in
        TEST_ENVIRONMENT so that it is passed to (old testsuite) tests.
        * libltdl/config/ltmain.m4sh (func_cygpath): New function.
        (func_init_to_host_pathlist_cmd): New function.
        (func_to_host_path): Refactored to... (now uses eval
        $to_host_path_cmd).
        (func_wine_to_win32_path): Here. New function.
        (func_msys_to_win32): Here. New function.

2009-02-17  Charles Wilson  <...>

        [cygwin|mingw] fix dlpreopen with --disable-static
        * libltdl/config/general.m4sh: Update copyright year.
        (func_tr_sh): New function.
        * libltdl/config/ltmain.m4sh (func_generate_dlsyms) [cygwin|mingw]:
        Obtain DLL name corresponding to import library by using value
        stored in unique variable libfile_$(transliterated implib name).
        If that fails, use $sharedlib_from_linklib_cmd to extract DLL
        name from import library directly. Also, properly extract dlsyms
        from the import library.
        (func_mode_link) [cygwin|mingw]: Prefer to dlpreopen DLLs
        over static libs when both are available.  When dlpreopening
        DLLs, use linklib (that is, import lib) as dlpreopen file,
        rather than DLL. Store name of associated la file in
        unique variable libfile_$(transliterated implib name)
        for later use.
        (func_win32_libid): Accomodate pei-i386 import libs
        as well as pe-i386.
        (func_cygming_dll_for_implib): New function.
        (func_cygming_dll_for_implib_fallback): New function.
        (func_cygming_dll_for_implib_fallback_core): New function.
        (func_cygming_gnu_implib_p): New function.
        (func_cygming_ms_implib_p): New function.
        * libltdl/m4/libtool.m4 (_LT_CMD_GLOBAL_SYMBOLS): Adjust sed
        expressions for lt_cv_sys_global_symbol_to_c_name_address and
        lt_cv_sys_global_symbol_to_c_name_address_lib_prefix
        as trailing space after module name is optional.
        (_LT_LINKER_SHLIBS) [cygwin|mingw][C++]: Set exclude_expsyms
        correctly for $host. Simplify regular expression in
        export_symbols_cmds.
        (_LT_LINKER_SHLIBS) [cygwin|mingw|pw32][C]: Set exclude_expsyms
        correctly for $host. Enable export_symbols_cmds to identify
        DATA exports by _nm_ prefix.
        (_LT_CHECK_SHAREDLIB_FROM_LINKLIB): New macro sets
        sharedlib_from_linklib_cmd variable.
        (_LT_DECL_DLLTOOL): New macro ensures DLLTOOL is always set.
