GNU libtool 是一个通用库支持脚本

	* configure.in (date): echo the version number during
	configuration, and show $date for cvs versions.

	* Makefile.am ($(srcdir)/ltconfig): Oops.  cvs co keyword
	expansion ate the sed expression! Changed sed separator to '%'
	because there are '/' in the date.  Added missing '\(' to search
	expression.  Inserted a null string to stop cvs from expanding it
	next time =)O|
	($(srcdir)/ltmain.sh): ditto.

1999-01-22  Alexandre Oliva  <[e-mail]>

	* Makefile.am (TSDEPS_DIST): dist-time dependencies for timestamps
	(timestamps, update-timestamps): check whether TSDEPS_DIST are
	up-to-date and update ltconfig and ltmain.sh if needed
	(ltconfig, ltmain.sh): depend on TSDEPS; replace @TIMESTAMP@ with
	the Date tag in the ChangeLog
	(TSDEPS): empty unless overridden by update-timestamps
	* ltconfig.in, ltmain.in (TIMESTAMP): append timestamp to most
	references to VERSION

1999-01-22  Gary V. Vaughan  <[e-mail]>

	* ltmain.in (ild): Revert the change which allowed libtool to
	link libraries with dependencies on .la libs.
	* NEWS: Removed reference to win32, incase 1.3 ships before
	ild is ready.
	* doc/PLATFORMS: Removed i686-pc-cygwin32, for the same reason.
	* doc/libtool.texi: Removed win32 refs, for the same reason.

1999-01-22  Alexandre Oliva  <[e-mail]>

	* ltmain.in (Xsed): add 1 to Xsed definition that goes into
	temporary wrapper scripts
	* libtool.m4: we don't have Xsed here, expand it manually
	Reported by Pavel Roskin <[e-mail]>

1999-01-22  Edouard G. Parmelan  <[e-mail]>

	* ltmain.in (finalize_hardcode_libdirs, finalize_rpath): in
	platforms that use -rpath, programs must be finalized at
	installation time, otherwise build-tree programs will
	prefer installed libraries over build-tree ones

1999-01-22  Alexandre Oliva  <[e-mail]>

	* mdemo/Makefile.am (../libltdl/libtool): if it does not exist,
	the sub-make for libltdlc.la will take care of it, but we must at
	least provide an empty rule for it, otherwise the sub-make will
	never run

	* demo/configure.in, demo/Makefile.am (DLPREOPEN): reverted; it
	didn't make any difference.

1999-01-21  Gary V. Vaughan  <[e-mail]>

	* THANKS: Added Chris Laas <[e-mail]>
	
	From Chris Laas <[e-mail]>
	* ltmain.in (compile):  corrected a typo in compile mode which
	caused "gcc: unrecognized option -c-fPIC" errors due to a missing
	space.

1999-01-21  Alexandre Oliva  <[e-mail]>

	* libltdl/configure.in: reintroduce code to detect native library
	extension
	* libltdl/ltdl.c (lt_dlopen): if a .la file name is given, that's
	all.  Otherwise, lt_dlopen now tries to append .la first.  If this 
	fails, it tries the given filename, and, at last, tries to append
	the native library extension to the given filename.
	* doc/libtool.texi (lt_dlopen): explain new lookup strategy

	* libltdl/ltdl.c: major rewrite to avoid almost all fixed-size
	buffers; only `tmp' in lt_dlopen remained.  But the code got ugly
	:-(

	* ltconfig.in (linux-gnu*, finish_cmds): remove erroneous backslash

	* demo/configure.in: set DLPREOPEN to -dlopen if we don't have
	shared libraries
	* demo/Makefile.am (DLPREOPEN): use instead of -dlpreopen
	(STATIC): use $(STATIC), not @STATIC@
	* mdemo/Makefile.am (STATIC): ditto

	* tests/demo-shared.test, tests/demo-static.test: new tests
	* tests/mdemo-shared.test, tests/mdemo-static.test: ditto
	* tests/Makefile.am: ditto
	* doc/libtool.texi: document them
	* demo/Makefile.am, mdemo/Makefile.am (STATIC): do not use
	-static unconditionally, it can't work with --disable-static
	* demo/configure.in, mdemo/configure.in: check whether libtool was 
	configured to build static libraries and, if not, set STATIC to an 
	empty string

1999-01-20  Alexandre Oliva  <[e-mail]>

	* ltmain.in (module, droppeddeps): if libtool could not satisfy
	all dependencies of a module, it will only build a static version
	of it, and display a warning message

1999-01-20  Erez Zadok <[e-mail]>

	* ltconfig.in (aix4*, with_gcc, archive_cmds): fix typo in Andrey
	Slepuhin's last patch

1999-01-20  Alexandre Oliva  <[e-mail]>

	* Makefile.am (@DIST_MAKEFILE_LIST@): work around Ultrix /bin/sh bug
	* tests/nomode.test (must specify a MODE): ditto
	Reported by Rainer Orth <[e-mail]>
	* THANKS: Added Rainer Orth

1999-01-20  Rainer Orth  <[e-mail]>

	* ltconfig.in: No known version of Solaris 2 hardcoded -L paths.

1999-01-20  Erez Zadok <[e-mail]>

	* ltmain.in: s/n\'t/ not/
	* doc/PLATFORMS: updates for sunos4/m68k and aix

1999-01-20  Andrey Slepuhin  <[e-mail]>

	-bnoentry option to linker when building a shared library

1999-01-20  Alexandre Oliva  <[e-mail]>

	* ltmain.in (file_magic): follow soft-links before running `file'
	on the candidate library; try to avoid entering endless loop
	Suggested by Nix <[e-mail]>
	
	* ltconfig.in (linux*, solaris*, bsdi4*, sys_lib_search_path):
	remove expansion of $LD_LIBRARY_PATH
	* ltmain.in (lib_search_path): append the expansion of $shlibpath_var
	* doc/libtool.texi: document it

	* THANKS: Added Steven Schultz

1999-01-20  Steven M. Schultz <[e-mail]>

	* ltconfig.in (bsdi4*, check_shared_deplibs_method): file_magic
	(bsdi4*, sys_lib_search_path): add /shlib and other dirs

1999-01-20  Alexandre Oliva  <[e-mail]>

	* cdemo/main.c (main): use K&R definition syntax
	* mdemo/main.c (test_dl, main): ditto
	(test_dl): casts return value of lt_dlsym to appropriate types

	* ltmain.in (dlsyms): #define const to nothing if not __STDC__

	* ltconfig.in (global_symbol_pipe): #define const to nothing if
	not __STDC__

	* demo/dlmain.c (main): cast s->address to the appropriate pointer
 	types, otherwise StunOS4's cc refuses to compile it

	* ltconfig.in (sunos4*, without_gnu_ld, with_gcc, archive_cmds):
 	add -fPIC, because libgcc is multilibbed, and we want the PIC
 	version of it for shared libraries, otherwise ld complains

	* demo/dlmain.c (main): add missing const to declaration of name

	* libltdl/ltdl.c (find_module): remove the libdir argument, and
	try to  open library only as old_name and dir/dlname
	(lt_dlopen): use `installed' variable in .la file to decide
	whether to use libdir or objdir
	
	* demo/configure.in (AC_C_CONST): added, for portability
	* mdemo/configure.in (AC_C_CONST): ditto
	* libltdl/configure.in (AC_C_CONST, AC_C_INLINE): ditto
	* libltdl/ltdl.c (LTDL_FILENAME_MAX): use FILENAME_MAX if defined
	(FILENAME_MAX): replace all explicit uses with LTDL_FILENAME_MAX
	(presym_free_symlists, trim): don't return void, for portability
	(lt_dlgetsearchpath): replace (void) with __P((void))

	* ltmain.in (compile): when compiling both PIC and non-PIC, write
 	the PIC object to .libs/.lo and only rename it to .lo after
 	compiling the .o, to avoid fooling make dependencies

	* mdemo/main.c (LTDL_PREOPENED_SYMBOLS): remove

1999-01-20  Gary V. Vaughan  <[e-mail]>

	* TODO: Added inter-library deps for ltlibs.

	* THANKS: Added Vladimir Kushnir.

	* ltconfig.in (freebsd3*): Define `deplibs_check_method' and
	`file_magic_command' for freebsd-elf.

1999-01-20  Alexandre Oliva  <[e-mail]>

	* TODO: should we also build a `static' copy of a convenience
 	library out of .o files?

	* ltconfig.in (bsdi4*, netbsd*, uts4*, library_names_spec,
	soname_spec): removed duplicate dot before $major
	Reported by Steven M. Schultz <[e-mail]> (bsdi4*)

	* THANKS: added Manfred Weichel

1999-01-20  Manfred Weichel  <[e-mail]>

	* ltconfig.in (sysv5*): same as sysv4.3*

1999-01-20  Alexandre Oliva  <[e-mail]>

	* libltdl/ltdl.c (lt_dlopen): properly detect error condition when
	full pathname of non-libtool library is provided
	
	* libltdl/configure.in (libltdl_cv_preloaded_symbols,
	HAVE_PRELOADED_SYMBOLS): test whether we support -dl*open
	* libltdl/ltdl.c (!HAVE_PRELOADED_SYMBOLS, lt_preloaded_symbols):
	define it to an empty list if libtool won't generate it, so as to
	avoid link errors.  This will cause silent dlopening failures, but 
	maybe this is better than failing to link the program...

	* libltdl/ltdl.h (LTDL_PRELOADED_SYMBOLS): remove it; better to
	declare lt_preloaded_symbols
	* doc/libtool.texi (LTDL_PRELOADED_SYMBOLS): ditto

	* ltmain.in (dlpredeps): removed, reverting 1999-01-17's change

1999-01-19  Alexandre Oliva  <[e-mail]>

	* libltdl/Makefile.am (Makefile): depend on libtool

	* ltmain.in (lt_preloaded_setup): function added to symbol list
	source file to work around FreeBSD problem

	* Makefile.am (check-local): depend on libltdl/Makefile

	flags to LDADD
	* doc/libtool.texi (Using Automake): how to add -dlopen to LDADD

1999-01-19  Gary V. Vaughan  <[e-mail]>

	From Andrey Slepuhin <[e-mail]>
	* ltmain.in (hardcode_action) Oops, misapplied the patch!
	
	* ltconfig.in (compile_dependencylbs): removed this
	variable and pick up the library dependencies from $deplibs.
	* ltmain.in (compile_dependencylibs): removed this
	variable, use deplibs to hold these dependencies.

	From Andrey Slepuhin <[e-mail]>
	* ltmain.in (hardcode_action) make sure deplibs is set to include
	all the	extra libs added to compile_command.

1999-01-18  Alexandre Oliva  <[e-mail]>

	* libtool.m4 (LIBTOOL_DEPS): set it
	* libltdl/configure.in (LIBTOOL_DEPS): AC_SUBST it
	* libltdl/Makefile.am (libtool): use it
	* doc/libtool.texi (AM_PROG_LIBTOOL): document it

	* Makefile.am (libltdl.tar.gz): don't create it as part of the
	build, since it is likely to become stale if we do
	(install-data-hook): create and install libltdl.tar.gz, without
	depending on GNU tar
	Reported by Manfred Weichel <[e-mail]>

1999-01-17  Thomas Tanner  <[e-mail]>

	* libltdl/Makefile.am: incremented the version, removed
	  libtool dependency so that it can be build independently
	* libltdl/configure.in: removed LTDL_SHLIB_EXT hack, 
	  set version to 1.0, use AM_MAINTAINER_MODE, 
	  DLPREOPEN is always supported, check for libtool's objdir variable
	  (LTDL_OBJDIR)
	* libltdl/ltdl.c: some cleanups (moved constants to the beginning
