	GNU libtool 1.4.2 was released.

	* configure.in: Bumped version to 1.4.2.
	* config.sub, config.guess:  Synchronised from ftp.gnu.org.
	* NEWS: Updated.

2001-09-11  Gary V. Vaughan  <[e-mail]>,  Albert Chin <[e-mail]>.  Tim Van Holder  <[e-mail]>

	* libtool.m4 (no_undefine_flag) [solaris*]:  Don't set this flag
	if GCC < 3.0 with native ld, which introduces a dependency on
	libgcc.a under certain circumstances, which in turn violates
	-no-undefined.  Also display a prominent configure time warning if
	the buggy combination of GCC and ld is detected.
	(AC_LIBTOOL_HEADER_ASSERT):  libltdl falls foul of this bug
	because assert requires __eprintf from libgcc.a.  This macro
	detects the combination of GCC and ld that produce this problem,
	and pretends that assert.h does not exist...
	* libltdl/ltdl.c (HAVE_ASSERT_H):  ...so that assertions can be
	disabled in libltdl.  Otherwise the library would only be useable
	when linking using gcc, or by manually adding libgcc.a to the link
	line of the application that uses libltdl.
	* ltdl.m4 (AC_LIB_LTDL):  Require AC_LIBTOOL_HEADER_ASSERT.
	* doc/PLATFORMS:  Updated.

2001-09-11  Daniel Harvey <[e-mail]>

	* libtool.m4 (ltdll_cmds): [$]0 doesn't appear to translate through
	the script correctly, change to $''0

2001-09-11  Gary V. Vaughan  <[e-mail]>

	* libltdl/configure.in (AC_CONFIG_HEADER): Use config-h.in for DOS
	compatibility.

	* libtool.m4: Add missing M4 quotation to $1 of AC_DEFUN calls.

	* libltdl/configure.in (AM_INIT_AUTOMAKE): Bump libltdl version to
	1.2.
	* libltdl/Makefile.am (libltdl_la_LDFLAGS):  Bump libtool library
	version info to 4:0:1.

2001-09-10  Gary V. Vaughan  <[e-mail]>

	* libtool.m4 (_LT_AC_LIBTOOL_SYS_PATH_SEPARATOR):  Oops.  We
	really ought to set PATH_SEPARATOR in here somewhere.
	(AC_PROG_LD): Don't forget to AC_REQUIRE it!  Be careful not to
	set IFS="${IFS}$PATH_SEPARATOR" for PATH splitting, otherwise
	spaces in directory names will be lost.
	(AC_PROG_NM): Dittp.
	* ltmain.in: Default IFS once, at the start.
	Reported by Akim Demaille <[e-mail]>

2001-09-10  Brad  <[e-mail]>

	* ltmain.in (-lc_r): Style improvement.

	* doc/libtool.texi: Remove obsolete references to ltconfig.
	* bootstrap: Don't bother creating an empty ltconfig and then
	removing it.
	* tests/quote.test: s/ltconfig/\$0/

2001-09-09  Gary V. Vaughan  <[e-mail]>

	From Brad <[e-mail]>:
	* libtool.m4: Use Autoconf square bracket quoting style
	consistently throughout.

2001-09-07  Gary V. Vaughan  <[e-mail]>

	* bootstrap: Cleanup `autom4te' and `libtool' so that we don't
	get caught by something from a previous build.

	* libtool.m4 (archive_cmds, archive_expsym_cmds) [solaris*]: Revert
	my 2001-09-06 patch.
	(no_undefined_flag)i [solaris*]: Revert Alexandre's 2001-04-11 patch.

	* libltdl/acconfig.h:  Removed.  Obsoleted with modern Automake
	(i.e. 1.4 or better).

	* libltdl/ltdl.c (foreach_dirinpath): argz_len should be a size_t.
	Reported by Albert Chin <[e-mail]>

2001-09-06  Gary V. Vaughan  <[e-mail]>

	* libtool.m4 (archive_cmds, archive_expsym_cmds) [solaris*]: Changing
	no_undefined_flag from `-z text' to `-z defs' (see entry below at
	2001-04-11  Alexandre Oliva  <[e-mail]>) has a problem.
	when linking a shared library with gcc calling /usr/ccs/bin/ld (eg.
	the gcc supplied with Solaris 8 companion CD), using the flag
	-no-undefined, shared library linking will always fail because of
	the unresolved symbols from libgcc.a.  Consequently we have to
	provide a path to libgcc.a when linking shared libraries in
	conjunction with -no-undefined!

	From Michael Pruett <[e-mail]>:
	* libltdl/ltdl.c (find_module): `0' valued arguments to
	tryall_dlopen_module() must be explicitly cast to avoid compiler
	warnings on some environments.

2001-09-03  Gary V. Vaughan  <[e-mail]>

	* demo/Makefile.am (helldl):  Automake 1.4 can't find the target
	if we use helldl$(EXEEXT), and Automake 1.5 barfs unless we do.
	Using both targets to the left of the colon seems to work though!

2001-09-03  Brad  <[e-mail]>

	* ltdl.m4 [AC_LTDL_SYS_DLOPEN_DEPLIBS]: Teach ltdl about the
	behavior of OpenBSD's dlopen().

2001-09-03  Gary V. Vaughan  <[e-mail]>

	* configure.in: Bumped version to 1.4.1a.

	GNU libtool 1.4.1 was released.

	* configure.in: Bumped version to 1.4.1.
	* config.sub, config.guess:  Synchronised from ftp.gnu.org.
	* doc/texinfo.tex: Ditto.
	* NEWS: Updated.
	* TODO: Remove fixed bugs.

	* ltdl.m4 (AC_CHECK_TYPES):  This macro was introduced in Autoconf
	2.5x.  Backported a fallback implementation (directly to ltdl.m4)
	from Autoconf 2.50, so that we can still bootstrap with Autoconf
	2.13.

	From Marius Vollmer <[e-mail]>:
	* libltdl/ltdl.c (tryall_dlopen_module): Don't forget to propogate
	errors over recurse levels.

2001-09-03  Brad  <[e-mail]>

	* libtool.m4 [openbsd*]: More improvements to the OpenBSD port.

	* libtool.m4 (deplibs_check_method) [aix*]: Removed redundant
	setting of this variable.

2001-09-02  Gary V. Vaughan  <[e-mail]>

	From Albert Chin <[e-mail]>:
	* libtool.m4 (_LT_AC_LANG_C_CONFIG) [aix4*]: Be careful with
	shared namespaces for static and shared libs.
	(AC_LIBTOOL_DLOPEN_SELF): If all else fails, try dld_link from GNU
	DLD.

2001-09-02  Christopher Pfisterer <[e-mail]>

	* libtool.m4, ltmain.in: Linker flag and version numbering fixes
	for darwin.

2001-09-02  Gary V. Vaughan  <[e-mail]>

	Backported the following patches from the development branch:

	Based on a patch from Marius Vollmer <[e-mail]>:
	* NEWS: updated.
	* ltdl.m4 (AC_LIB_LTDL): Check for unistd.h.
	* libltdl/ltdl.c: Include unistd.h if it exists.
	(LTDL_SEARCHPATH_VAR): Macro to prevent hardcoding
	"LTDL_LIBRARY_PATH".
	(LTDL_ARCHIVE_EXT): Macro to prevent hardcoding ".la".
	(archive_ext): Have only one copy of ".la" in the readonly
	segment of the compiled library.
	(find_handle_callback): Don't bother trying to dlopen the file if
	it doesn't exist.
	(find_handle): Don't bother searching for files if no search_path
	was supplied.
	(file_not_found): A new function to determine whether the last
	error was due to a file not found condition.
	(try_dlopen): Renamed from lt_dlopen() and changed to have the
	same footprint as tryall_dlopen.  This involved a minor rewrite of
	much of the internals of this function.
	(lt_dlopen): A new function wrapped arounf try_dlopen().
	(lt_dlopenext): If a file already has a suitable extension, don't
	bother adding additional extensions and trying to open those.
	Tidy up the rest of the code to prevent continued searching with
	an eventual FILE_NOT_FOUND when a genuine failure earlier in the
	search process could be legitimately reported.

	* libltdl/ltdl.c (argz_create_sep): Don't forget to include the
	terminating '\0' when counting argz_len.
	(argz_create_sep): When canonicalizing argz, don't forget to copy
	the terminating '\0', incase canonicalization has shortened argz.
	(argz_stringify): Don't covert the final '\0' to a separator.

	* libltdl/ltdl.c (lt_dlhandle_next): Now we can loop through all
	loaded module handles as originally intended.

	* libltdl/ltdl.c (lt_dlseterror): Oops.  This never worked
	either, due to a pair of typos.  Now fixed.

	* libltdl/ltdl.c (N_ELEMENTS):  Deleted.  How come nobody noticed
	there was no way this could have ever worked?
	(lt_dlcaller_set_data): Now that valid caller_ids must be
	non-zero, allocate an addition entry in the caller_data vector and
	use a zero valued key as the end marker.
	(lt_dlcaller_get_data): Iterate up to the end marker in one pass.

	* libltdl/ltdl.c (lt_dlcaller_register): Caller ids are allocated
	starting from value `1', so that clients can use a value of zero
	to indicate that libltdl has not yet initialised.

	* libltdl/ltdl.c (find_file_callback): Fix a multiple free()
	bug.
	(tryall_dlopen_module): Remove some unused variables.

	* libltdl/ltdl.c (lt_dlinsertsearchdir): Calculate the address
	of the end of user_search_path correctly.

	* libltdl/ltdl.c (rpl_argz_stringify): New fallback implementation.
	* ltdl.m4 (AC_LTDL_FUNC_ARGZ):  Test for argz_stringify in libc.
	* libltdl/ltdl.c (lt_argz_insertinorder): Renamed from
	lt_argz_insert to make room for...
	(lt_argz_insert): Wraps argz_insert with libltdl error handling.
	(lt_dlpath_insertdir): Insert new path elements into an
	argzized path.
	(lt_dlinsertsearchdir): New function to insert new search
	directories anywhere into user_search_path using the above.
	(lt_dladdsearchdir): Rewritten to use lt_dlpath_insertdir.
	* libltdl/ltdl.h (lt_dlinsertsearchdir): Prototype for export.
	* doc/libtool.texi (Libltdl interface): Document it.

2001-08-18  Brad  <[e-mail]>

	* ltmain.in: Do not remove -lm from deplibs for OpenBSD.

2001-08-05  Gary V. Vaughan  <[e-mail]>

	From Brad <[e-mail]>:
	* libtool.m4 (archive_cmds) [darwin, newsos, sysv4]: Replace
	1.3 era $linkopts references with $linker_flags.

	From Brad <[e-mail]>:
	* libtool.m4 [openbsd]:  OpenBSD can build modules without a `lib'
	prefix and version number.

2001-08-04  Gary V. Vaughan  <[e-mail]>

	From Edouard G. Parmelan <[e-mail]>
	* libtool.m4 [darwin, openbsd]: Fix quoting problems with
	unquoted [] expressions.

2001-07-29  Albert Chin-A-Young  <[e-mail]>

	* libtool.m4: Prefer shl_load to dlopen	on HP-UX because
	dlopen won't work properly without a patch.

2001-07-12  Dan McNichol  <[e-mail]>

	From albert chin <[e-mail]>
	* libtool.m4: Fix AIX run-time-linking when using gcc.

	From albert chin <[e-mail]>
	* ltmain.in: Fix a case where the lockfile is not removed, thus
	causing libtool to loop forever waiting for it to be removed.

2001-07-05  Gary V. Vaughan  <[e-mail]>

	* libtool.m4 (_LT_AC_LTCONFIG_HACK):  Revert to 1.3.x
	sematics, and always build static libs when the host machine
	cannot build shared libs.  Even if static libs were explicitly
	disabled.

	* libtool.m4 (AC_LIBTOOL_SYS_GLOBAL_SYMBOL_PIPE) [HPUX]: Define
	lt_cv_sys_global_symbol_to_c_name_address to be a sed expression
	for mangling the output of the symbol pipe into a brace delimited
	C declaration of symbol name and address.
	* ltmain.in: Use it to generate the fooS.c symbol name to address
	map.

2001-06-30  Gary V. Vaughan  <[e-mail]>

	Porting test improvements from multi-language-branch:
	* tests/defs: Find and set the value of CC probed by libtool.m4
	* tests/link-2.test: Use a .lo wrapper script, and the value of
	CC set by defs instead of hardcoding gcc.
	* tests/link.test: Use the value of CC set by defs instead of
	hardcoding gcc.
	* tests/quote.test: Ditto.
	* tests/suffix.test: Ditto.

	* libtool.m4 (_LT_AC_LTCONFIG_HACK) [aix*]: Always set
	lt_prog_compiler_wl to `-Wl'.
	Reported by Albert Chin-A-Young  <[e-mail]>

2001-06-29  Gary V. Vaughan  <[e-mail]>

	From Tim Van Holder <[e-mail]>
	* tests/suffix.test: Typo in 2nd for loop.

	From Bruno Haible <[e-mail]>
	* libtool.m4:  undefine the m4 builtin `symbols', so that the
	string `symbols' can be used in the rest of the code without
	causing errors with autoconf-2.13.

	From "Golubev I. N." <[e-mail]>
	* tests/Makefile.am (CPPLAGS): Typo. s/CPPLAGS/CPPFLAGS.

	* mdemo/Makefile,am (foo1_la_LIBADD): Add libsub.la, since foo1
	does use symbols from libsub.la -- only platforms that allow
	undefined symbols in libraries were able to cope with this
	previously.
	Reported by Robert Collins <[e-mail]>

	From "Golubev I. N." <[e-mail]>
	* libtool.m4 (AC_LIBTOOL_PROG_LD_SHLIBS) [sco3.2v5*]: Needs
	-wl,-Bexport to make self dlopen work.

	From Chris Leishman <[e-mail]>
	* libtool,m4 (_LT_AC_LTCONFIG_HACK) [darwin]:  Cheap hack to
	help fake a C++ compilation.

	From Bruno Haible <[e-mail]>
	* NEWS: Updated.
	* libtool.m4 (_LT_AC_LTCONFIG_HACK):  Make sure ac_objext is
	set to `lo' when testing for compiler output to *.lo filenames.

2001-06-28  Gary V. Vaughan  <[e-mail]>

	From  Alexander Bluhm  <[e-mail]>
	* libltdl/ltdl.c (lt_dlopen): Fix bad memory initialisation
	assumptions.

2001-06-27  Gary V. Vaughan  <[e-mail]>

	From [e-mail]:
	* NEWS: Updated.
	* libtool.m4 (_LT_AC_LTCONFIG_HACK) [openbsd]: Improved support
	for various openbsd platforms.
	* ltmain.in: Ditto,

2001-05-20  Peter Eisentraut  <[e-mail]>

	* libtool.m4 (allow_undefined_flag) [aix4* | aix5*]: Fix quote
	error.

	* ltmain.in (exec_cmd): New variable.  Don't exec programs within
	the big `case'; set the variable instead, and exec the cmd
	afterwards, so that the shell gets a chance to clean up here-doc
	files.
	* NEWS: Update.

2001-05-16  Alan Modra  <[e-mail]>

	* libtool.m4 (lt_cv_deplibs_check_method): pass_all for hppa*-linux.
