+
+* Noteworthy changes in release 2.5.3 (2024-09-25) [stable]
+
+** New features:
+
+  - Add 'aarch64' support to the file magic test, which allows for
+    shared libraries to be built with Mingw for aarch64.
+
+** Bug fixes:
+
+  - The configure options --with-pic and --without-pic have been renamed
+    to --enable-pic and --disable-pic, respectively.  The old names
+    --with-pic and --without-pic are still supported, though, for
+    backward compatibility.
+
+  - The configure option --with-aix-soname has been renamed to
+    --enable-aix-soname.  The old name --with-aix-soname is still

+
+* Noteworthy changes in release 2.5.2 (2024-08-29) [beta]
+
+** Bug fixes:
+
+  - Use shared objects built in source tree instead of the installed
+    versions for more reliable testing.
+
+  - Fix test in bug_62343.at for confirmed Cygwin/Mingw32 where the
+    incorrect architecture version of a compiler was generating
+    object files that could not be linked with a library file.
+
+  - Fix typos found with codespell.
+
+** Changes in supported systems or compilers:
+
+  - Add support for 32-bit mode on FreeBSD/powerpc64.
+
+
+* Noteworthy changes in release 2.5.1 (2024-07-25) [beta]
+
+** New features:
+
+  - Support C++17 compilers in the C++ tests.
+
+  - Add sysroot to library path for cross builds.
+
+** Important incompatible changes:
+
+  - Autoconf 2.64 is required for libtool.m4 to use AS_VAR_APPEND.
+
+** Bug fixes:
+
+  - Fix for uninitialized variable in libtoolize.
+
+  - Skip Fortran/C demo tests when using Clang with fsanitize to
+    avoid an incompatible ASan runtime.
+
+  - Updated documentation for testing.
+
+  - Fix failing test to account for program-prefix usage.
+
+  - Replaced a deprecated macro to remove warning messages in the
+    testsuite logs.
+
+  - Fix number of arguments for AC_CHECK_PROG call.
+
+  - Fix test failures with no-canonical-prefixes flag by checking
+    if the flag is supported first.
+
+  - Fix test failures with no-undefined flag by checking host OS
+    before appending the flag.
+
+  - Skip test when passing CXX flags through libtool to avoid test
+    failure on NetBSD.
+
+  - Remove texinfo warning for period in node name of pxref.
+
+  - Alter syntax in sed command to fix numerous test failures
+    on 64-bit windows/cygwin/mingw.
+
+  - Fix 'Wstrict-prototypes' warnings.
+
+  - Correct DLL Installation Path for mingw multilib builds.
+
+  - Fix '--preserve-dup-deps' stripping duplicates.
+
+  - Disable chained fixups for macOS, since it is not compatible with
+    '-undefined dynamic_lookup'.
+
+** Changes in supported systems or compilers:
+
+  - Support additional flang-based compilers, 'flang-new' and 'ftn'.
+
+
+* Noteworthy changes in release 2.5.0 (2024-05-13) [alpha]
+
+** New features:
+
+  - Pass '-fdiagnostics-color', '-frecord-gcc-switches',
+    '-fno-sanitize*', '-Werror', and 'prefix-map' flags.
+
+  - Pass the '-no-canonical-prefixes' linker flag.
+
+  - Pass '-fopenmp=*' for Clang to allow choosing between libgomp and
+    libomp.
+
+  - Pass '-shared-libsan', '-static-libsan', 'rtlib=*', and
+    'unwindlib=*' for Clang.
+
+  - Expanded process.h inclusion on Windows for more than the
+    proprietary MSVC compiler. Other alternative Windows compilers
+    also require process.h.
+
+  - Pass 'elf32_x86_64' and 'elf64_x86_64' to the linker on hurd-amd64.
+
+  - Recognize *-*-windows* config triplets.
+
+** Important incompatible changes:
+
+  - Removed test_compile from command line options.
+
+  - By default executables are created with the RUNPATH property for
+    the Android linker. RUNPATH works for libraries which are not
+    installed in system locations.
+
+  - Removed AC_PROG_SED fallback, as the macro has been supported
+    in Autoconf since the 90's.
+
+** Bug fixes:
+
+  - Check for space after -l, -L, and -R linker flags.
+
+  - Updated documentation for tests, the demo directory, and
+    elsewhere.
+
+  - Fixed Solaris 11 builds.
+
+  - Clean trailing "/" from sysroot path.
+
+  - Fixed shared library builds for System V.
+
+  - Added mingw to the list of systems not requiring libm.
+
+  - Fixed support for nios2 systems.
+
+  - Fixed linker check for '--whole-archive' support for linkers other
+    than ld.
+
+  - Use -Fe instead of -o with MSVC to avoid deprecation warnings.
+
+  - Improved reproducibility of libtool scripts.
+
+  - Avoided MinGW warning by adding CRTIMP.
+
+  - Improved grep portability.
+
+  - Fixed cross-building warnings when checking for file.
+
+** Changes in supported systems or compilers:
+
+  - Removed support for bitrig (*-*-bitrig*).
+
+  - Added support for flang (Fortran LLVM-based) compilers.
+
+
+* Noteworthy changes in release 2.4.7 (2022-03-16) [stable]
+
+** New features:
+
+  - Libtool script now supports (configure-time and runtime) ARFLAGS
+    variable, which obsoletes AR_FLAGS.  This is due to naming conventions
+    among other *FLAGS and to be consistent with Automake's ARFLAGS.
+
+  - Gnulib testsuite is enabled and run during 'make check'.
+
+  - Support the Windows version of the Intel C Compiler (icl) in
+    libtool script.
+
+  - Pass '-fsanitize=*' flags for GCC and LLVM, and '-specs=*' for GCC
+    to linker.
+
+  - Pass '-Xassembler=*' and '-Wa,*' flag to compilers and linkers.
+
+  - The variable 'FILECMD' with default value of '/usr/bin/file' was used to
+    replace existing hard coded references to '/usr/bin/file'.
+
+  - Add MidnightBSD support.
+
+** Important incompatible changes:
+
+  - Libtool changed ARFLAGS/AR_FLAGS default from 'cru' to 'cr'.
+
+  - Do not pass '-pthread' to Solaris linker.
+
+  - 'libtool' and 'libtoolize' scripts now use '#! /usr/bin/env sh' shebang.
+    Previously '#! /bin/sh' was used, which presents challenges for
+    containerized environments.
+
+** Bug fixes:
+
+  - Fix significant slowdown of libtoolize for certain projects (regression
+    introduced in 2.4.3 release) caused by infinite m4 macro recursion.
+
+  - Mitigate the slowdown of libtool script (introduced in v2.4.3) caused by
+    increased number of calls to '$SED $sed_quote_subst' (bug#20006).
+
+  - Properly parse and export TLS symbols on AIX.
+
+  - Various bug fixes surrounding use of 'sed'.
+
+  - Darwin systems set proper "allow undefined" flag on OSX 11, and
+    PowerPC 10.5.
+
+  - Removed some deprecated tests related to 'Makefile.inc' files.
+
+* Noteworthy changes in release 2.4.6 (2015-02-15) [stable]
+
+** New features:
+
+  - LT_SYS_LIBRARY_PATH can be set in config.site, or at configure time
+    and persists correctly in the generated libtool script.
+
+** Bug fixes:
+
+  - Fix a race condition in ltdl dryrun test that would cause spurious
+    random failures of that test.
+
+  - LT_SYS_DLSEARCH_PATH is munged correctly.
+
+
+* Noteworthy changes in release 2.4.5 (2015-01-19) [stable]
+
+** New features:
+
+  - Libtoolize searches for the best available M4 on the user PATH at
+    runtime, rather than settling for the first one found.
+
+  - Support munging sys_lib_dlsearch_path_spec with LT_SYS_LIBRARY_PATH
+    environment variable.
+
+** Bug fixes:
+
+  - Bail out at configure time if the installed M4 is not sufficient
+    for the purposes of libtoolize.
+
+  - freebsd-elf library versioning was upgraded incorrectly in 2.4.4,
+    but now works properly again.
+
+  - Fix a 2.4.4 regression so that libltdl subprojects do not warn
+    about missing libltdl/libltdl directory as in prior releases.
+
+  - When using Sun C++ on Solaris or GNU/Linux we used to set libtool's
+    postdeps permanently, based on the contents of $CXX and $CXXFLAGS at
+    configure time, which was brittle and error-prone.  Now, we no
+    longer check for a SunCC ABI at configure time, but augment the
+    postdeps at libtool time based on the current invocation flags on
+    each call.
+
+** Changes in supported systems or compilers:
+
+  - /usr/local prefixed rpaths are now added to the link-line on
+    ia64-hp-hpux*, because the default system runtime loader path does
+    not contain them.
+
+  - Previously, when using Sun C++ on Solaris or GNU/Linux, `-Cstd -Crun`
+    flags were added to $postdeps unless CXX or CXXFLAGS contained
+    `-library=stlport4`.  Newer releases have added other compiler flags
+    that are also incompatible with `-Cstd -Crun`, so now we don't add
+    them if any of `-std=c++[0-9][0-9]`, `-library=stdcxx4` or
+    `-compat=g` were found in CXX or CXXFLAGS when the Sun C++ compiler
+    is detected.

-## ------ ##
-## Usage. ##
-## ------ ##
-
-# This file is a library for parsing options in your shell scripts along
-# with assorted other useful supporting features that you can make use
-# of too.
-#
-# For the simplest scripts you might need only:
-#
-#   #!/bin/sh
-#   . relative/path/to/funclib.sh
-#   . relative/path/to/options-parser
-#   scriptversion=1.0
-#   func_options ${1+"$@"}
-#   eval set dummy "$func_options_result"; shift
-#   ...rest of your script...
-#
-# In order for the '--version' option to work, you will need to have a
-# suitably formatted comment like the one at the top of this file
-# starting with '# Written by ' and ending with '# warranty; '.
-#
-# For '-h' and '--help' to work, you will also need a one line
-# description of your script's purpose in a comment directly above the
-# '# Written by ' line, like the one at the top of this file.
-#
-# The default options also support '--debug', which will turn on shell
-# execution tracing (see the comment above debug_cmd below for another
-# use), and '--verbose' and the func_verbose function to allow your script
-# to display verbose messages only when your user has specified
-# '--verbose'.
-#
-# After sourcing this file, you can plug processing for additional
-# options by amending the variables from the 'Configuration' section
-# below, and following the instructions in the 'Option parsing'
-# section further down.
-
-## -------------- ##
-## Configuration. ##
-## -------------- ##
-
-# You should override these variables in your script after sourcing this
-# file so that they reflect the customisations you have added to the
-# option parser.
-
-# The usage line for option parsing errors and the start of '-h' and
-# '--help' output messages. You can embed shell variables for delayed
-# expansion at the time the message is displayed, but you will need to
-# quote other shell meta-characters carefully to prevent them being
-# expanded when the contents are evaled.
-usage='$progpath [OPTION]...'
-
-# Short help message in response to '-h' and '--help'.  Add to this or
-# override it after sourcing this library to reflect the full set of
-# options your script accepts.

-   -W, --warnings=CATEGORY

-   -v, --verbose      verbosely report processing

-@node Bootstrap
-@chapter Bootstrap
-
-The process of executing the various tools required to bring all the
-generated files up to date in a directory freshly checked out from
-source control can be quite involved.  Many GNU projects use
-@command{bootstrap} script to execute some or all of the following in the
-correct order: @command{gnulib-tool}, @command{autopoint},
-@command{libtoolize}, @command{autoreconf}. Often there's also
-additional file-processing and assorted book-keeping that also falls
-under the control of @command{bootstrap}, but it's wasteful for the
-maintainers of all these projects to manually reinvent a custom script
-on a case-by-case basis.
-
-Gnulib is designed to provide a central library of exemplar
-implementations to promote the sharing of useful common code among
-GNU project maintainers. However, the bootstrapping needs of these
-projects vary enormously, so Gnulib's @command{bootstrap} needs to be
-extremely @strong{customisable} and extensible, with less effort than
-would be otherwise required to invent an ad-hoc solution.

-
-
-@node Customisation
-@section Customisation
-
-There are four distinct ways to customize the functionality of
-@command{bootstrap}, all requiring creation of a @file{bootstrap.conf}
-file in the same directory as the imported @command{bootstrap} script
-itself.
-
-@menu
-* Configuration Variables::
-* Require Variables::
-* Hook Functions::
-* Function Replacement::
-@end menu
-
-
-@node Configuration Variables
-@subsection Configuration Variables
-
-For all but the more complex customisations, you need only change
-the value of a selection of the following shell variables in
-@file{bootstrap.conf}, to reflect whatever is appropriate to your
-package.
-
-@example
-    vc_ignore=.gitignore
-@end example
-
-@table @code
-
-@cnindex buildreq
-@item buildreq
-A newline-delimited list of triples of @strong{programs} (that must
-accept the option @option{--version} without hanging or failing), the
-@strong{minimum version required} (or just `-' in the version field if
-any version will be sufficient) and @strong{homepage URL (to
-help users locate missing packages)
-
-@smallexample
-buildreq='
-        git        1.5.5   http://git-scm.com
-        help2man   1.29    http://www.gnu.org/s/help2man
-'
-@end smallexample
-
-If you specify a minimum version of Autoconf with @code{AC_PREREQ},
-that version will be checked automatically without needing to be
-listed in @code{buildreq}.  Similarly for a minimum Automake version
-declared with @code{AM_INIT_AUTOMAKE}, Libtool version with
-@code{LT_PREREQ}, or Autopoint version with @code{AM_GNU_GETTEXT_VERSION}.
-
-If @code{AB_INIT} is declared in @file{configure.ac}, then a versionless
-requirement for Autobuild is added automatically, and finally if there
-are any diff files under @code{local_gl_dir}, then a versionless
-requirement for patch is also added.
-
-When there are backwards incompatibilities in a newer build-tool
-release, you can pin the version requirement for your program by
-prefixing the version number field in buildreq with a single '='
-character (no spaces).
-
-When @command{bootstrap} is invoked, it will check that all the listed
-and automatically added tools are available at the given minimum version,
-or else bail out with a diagnostic.
-
-
-@cnindex buildreq_readme
-@item buildreq_readme
-Name of a file containing instructions on installing missing packages
-required in @code{buildreq}. Usually, the instructions at the given
-URL should be sufficient, though some projects add additional notes
-in @file{HACKING}.
-
-@smallexample
-buildreq_readme=README-hacking
-@end smallexample
-
-
-@cnindex build_aux
-@item build_aux
-This is automatically extracted from the @code{AC_CONFIG_AUX_DIR}
-declaration in @file{configure.ac}, though you can specify it in
-@file{bootstrap.conf} if you don't otherwise want to declare
-@code{AC_CONFIG_AUX_DIR} in @file{configure.ac}.
-
-@cnindex macro_dir
-@item macro_dir
-This is automatically extracted from @file{configure.ac}, or if
-neither @code{AC_CONFIG_MACRO_DIRS} nor @code{AC_CONFIG_MACRO_DIR} is
-declared there, the option immediately following the first @samp{-I}
-from @code{ACLOCAL_AMFLAGS} in @file{Makefile.am} is used as a last
-resort. If you don't want to declare the macro directory in any of
-those places, then you can specify it in @file{bootstrap.conf} by
-using the @code{macro_dir} variable.
-
-@smallexample
-macro_dir=acm4
-@end smallexample
-
-
-@cnindex package
-@item package
-This is automatically extracted by downcasing the first argument to
-@code{AC_INIT} in @file{configure.ac}, though you can override it here
-if you prefer.
-
-@cnindex package_name
-@item package_name
-This is automatically extracted from the first argument to
-@code{AC_INIT} in @file{configure.ac}, though you can override it here
-if you prefer.
-
-@cnindex package_version
-@item package_version
-This is automatically extracted from the second argument to
-@code{AC_INIT} in @file{configure.ac}, though you can override it here
-if you prefer.
-
-@cnindex package_bugreport
-@item package_bugreport
-This is automatically extracted from the third argument to
-@code{AC_INIT} in @file{configure.ac} if given, though you can override
-it here if you prefer.

-These are normally extracted from @file{gnulib-cache.m4}, regardless of
-their values in @file{bootstrap.conf}.
-
-When that file is not yet created, then @command{bootstrap} will
-fall-back automatically to the gnulib defaults; unless you set
-alternative values here in @file{bootstrap.conf}.
-
-If you check @file{gnulib-cache.m4} into your repository, then these
-values will be extracted automatically. @xref{Usage Patterns}, for more

-needs to be created, otherwise they are ignored and the values stored in
-@file{.gitmodules} are used instead.

-Additional @command{xgettext} options to use.  Gnulib might provide you

-@end itemize
-
-
-@node Require Variables
-@subsection Require Variables
-
-Many of the functions in @command{bootstrap} should not be executed more
-than once, which is achieved by storing the name of that function in a
-variable and then calling it with:
-
-@smallexample
-$require_gnulib_tool
-@end smallexample
-
-At this stage, the value of the variable is interpreted as a function
-call by the shell, and the named function then runs.  Under normal
-circumstances, functions that are called in this way always set their
-associated variable name to simply @samp{:} so that subsequent
-occurrences of, in this instance, @code{$require_gnulib_tool} have no
-further effect.
-
-That means you can easily skip any functions that are called like this
-by unconditionally setting the require variable to @samp{:} in your
-@file{bootstrap.conf}. So, for example, if your package makes no use of
-@command{gnulib-tool}, you can add the following to your
-@file{bootstrap.conf}:
-
-@smallexample
-require_gnulib_tool=:
-@end smallexample
-
-You should be aware, however, that the function calls managed by this
-mechanism are designed to be called one time to ensure that some
-resource is available for use by the rest of any function that uses a
-@code{$require_some_resource} call.  Be careful to ensure that you
-remove any code paths that try to use that resource if you have
-effectively disabled it by setting its variable to @samp{:} early on.
-
-
-@node Hook Functions
-@subsection Hook Functions
-
-Many of the key functions in @command{bootstrap} will run one or more hook
-functions before they return.  Essentially, all that the entire script
-does is to define a lot of functions (some of which will run hooks),
-then source the contents of your @file{bootstrap.conf} customisations,
-and then finally run the @code{func_bootstrap} function.  Read the
-doc-comments above @code{func_bootstrap} in the @command{bootstrap} file,
-as well as the functions that it calls to find where you can hook your
-own functions, in order to be called during your customised execution of
-@command{bootstrap}.
-
-One of the trickier hook functions is set up to allow you to add
-additional arguments to the option parser for @command{bootstrap} without
-having to replace @code{func_parse_options} in its entirety:
-
-@smallexample
-my_silent_option ()
-@{
-    $debug_cmd
-
-    case $1 in
-      --silent|-s) opt_silent=:; shift ;;
-    esac
-
-    # return modified option list
-    func_quote_for_eval $@{1+"$@@"@}
-    func_run_hooks_result=$func_quote_for_eval_result
-@}
-func_add_hook func_parse_options my_silent_option
-@end smallexample
-
-
-@node Function Replacement
-@subsection Function Replacement
-
-In a few complex packages, you might find that some selection of
-functions called during the normal execution of @command{bootstrap} are
-wholly inappropriate for your project, where simply disabling
-@code{$require_some_resource} functions and hooking in additional code
-is not powerful enough to avoid or radically alter the parts of
-@command{bootstrap} you do not want.
-
-In that case you can simply write an entirely custom implementation of
-whatever function(s) you want to replace inside your
-@file{bootstrap.conf}, so that by the time @code{func_bootstrap} is
-called at the end of @command{bootstrap}, your new implementation is
-already in place.
-
-@example
-func_echo ()
-@{
-    # respect new --silent option
-    $opt_silent || echo "$progname: $*"
-@}
-@end example
-
-
-@node Usage Patterns
-@section Usage Patterns
-
-There are two ways to incorporate gnulib into your package, which are
-both supported by the @command{bootstrap} script.  Be sure that everyone
-working on your package is employing the same usage pattern, or things
-will turn bad!
-
-@menu
-* Configuration all kept in @file{bootstrap.conf}
-* Gnulib configuration stored in @file{gnulib-cache.m4}
-@end menu
-
-
-@node Configuration all kept in @file{bootstrap.conf}
-@subsection Configuration all kept in @file{bootstrap.conf}
-
-All the parameters for running @command{gnulib-tool} and other bootstrap-
-time commands are maintained in @file{bootstrap.conf}. This is the
-default usage pattern.
-
-In order for this to work, when you wish to add or remove a gnulib
-module from your package, amend the value of @var{gnulib_modules} in
-@file{bootstrap.conf} (and similarly for any other parameters) and rerun
-@command{bootstrap} to import everything anew.
-
-To avoid things getting out of sync, you should never run
-@command{gnulib-tool} directly.
-
-
-@node Gnulib configuration stored in @file{gnulib-cache.m4}
-@subsection Gnulib configuration stored in @file{gnulib-cache.m4}
-
-To implement this usage pattern, leave the value of @var{gnulib_modules}
-and the various @var{gl_xxx} variables empty in @file{bootstrap.conf}
-and call @command{gnulib-tool --import ...} from your shell, checking
-that @file{gnulib-cache.m4} reflects the values you wanted.  From now on
-you can either call @command{gnulib-tool --update} or rerun
-@command{bootstrap} whenever you want to resync the package modules with
-your local gnulib checkout.
-
-If you wish to add or remove a gnulib module from your package, call
-@command{gnulib-tool --import-add ...} or @command{gnulib-tool --import-
-remove} respectively.
-
-@node Known Bugs
-@section Known Bugs
-
-@itemize @bullet
-@item
-gnulib-tool has no @option{--force} option, so sometimes symlinks are
-left pointing to an old gnulib tree (even with @command{./bootstrap

-$ ./bootstrap --gnulib-srcdir=../gnulib --force
