GNU libtool 是一个通用库支持脚本

	* ltmain.in (dlpredeps): append dependencies from dlopened modules 
	(but not dlpreopened ones) after all explicitly linked libraries

	* ltconfig.in (need_lib_prefix, need_version,
 	deplibs_check_method): default to unknown, so that we're
 	remembered that this needs porting; unknown is interpreted as yes,
 	yes and none, respectively
	(freebsd2*, freebsd3*, sunos4*, need_version): set to yes
	(freebsd2*, freebsd3*, library_names_spec): libraries without a
	version number are not used by `ld'; add $versuffix;
	Reported by Ben Jackson <[e-mail]>
	* ltmain.in (deplibs_check_method): alias unknown to none
	(need_version): if vinfo was not provided and release info was,
	zero out versuffix only if we don't need_version.
	* doc/libtool.texi: document what `unknown' means

	* libltdl/ltdl.h (lt_dlpreopen_default): reverted to a macro
	without arguments, that calls lt_dlpreopen_default_ with
	lt_dlpreloaded_symbols
	* libltdl/ltdl.c (lt_dlpreopen_default_): renamed from
	lt_dlpreopen_default
	(find_module) tryall_dlopen old_name first, so that we don't
 	override statically linked symbols with dlopened ones

1999-01-15  Gary V. Vaughan  <[e-mail]>

	From Andrey Slepuhin <[e-mail]>
	* libtoolize.in (cd $pkgdatadir): Make sure we return the the
	working directory when this is done.

	From Andrey Slepuhin <[e-mail]>
	* ltconfig.in (aix): Use shared library support correctly on
	aix4*, and tweak the config for aix3.
	* NEWS: added aix3 and aix4 to list of hosts with improved
	support.
	* THANKS: added Andrey Slepuhin <[e-mail]>.

1999-01-15  Thomas Tanner  <[e-mail]>

	* Makefile.am (@DIST_MAKEFILE_LIST@): added a second '$' 
	  before abs_scrdir, removed ltconfig and ltmain.sh from
	  EXTRA_DIST (automake distributes them by default)
	
1999-01-14  Thomas Tanner  <[e-mail]>

	* autogen: moved faking of the libtool scripts before
	  the call of automake, so that ltconfig and ltmain.sh
	  are included in the distribution
	* ltconfig.in: when checking whether PIC is supported assume
	  only on HP/UX that warnings during compilation mean that
	  PIC is not supported (Thanks to Ron O'Hara)
	* THANKS: added Ron O'Hara
	  
1999-01-14  Alexandre Oliva  <[e-mail]>

	* Makefile.am: Moved ltconfig and ltmain.sh back into srcdir, and
	add them to the distribution.  Added work-around if `mv -f' fails.
	fix @AINCLUDE_M4_LIST@ and @DIST_MAKEFILE_LIST@ for relative and
	absolute specifications of srcdir

1999-01-14  Thomas Tanner  <[e-mail]>

	* libltdl/ltdl.c: added variable symbol prefix, added user-defined
	  library search path (can be set using lt_dlsearchpath()),
	  added default_preloaded_symbols which are independent of
	  lt_dlinit/exit
	* libltdl/ltdl.h: added lt_dlsearchpath() and
	  lt_dlpreopen_default()
	* mdemo/Makefile.am: use -export-dynamic until libtool 
	  and libltdl are able to handle module dependencies
	  
1999-01-14  Gary V. Vaughan  <[e-mail]>

	* THANKS: added Mark Elbrecht.
	* ltconfig.in (PATH_SEPARATOR): new variable to hold valid $PATH
	separator characters for the build host, to support DJGPP
	environment.
	* ltconfig.in: Use PATH_SEPARATOR instead of hardcoded `:'.
	Reported by Mark Elbrecht <[e-mail]>

	* cdemo/README: typo: mdemo->cdemo

1999-01-14  Thomas Tanner  <[e-mail]>

	* autogen: fake the libtool scripts to help fixing
	  the bootstrapping problem
	* Makefile.am: always configure libltdl, however after building
	  the libtool scripts, 
	  build the libtool scripts in builddir, not srcdir
	  (unfortunately this breaks building when srcdir!=objdir, 
	   but it was just plain wrong - needs to be fixed),
	  build and install libltdl.tar.gz,
	  copy acinclude.m4 instead of linking them, so that we 
	  can 'make dist' in libltdl,
	  fixed configuring of subdirectories
	* configure.in: removed --enable-ltdl-install - libltdl is supposed
	  to be installed by packages, not by libtool itself
	* libtoolize.in: new flags --ltdl and --ltdl-tar to install libltdl
	  in packages (--ltdl doesn't work yet),
	  install only the necessary libtool scripts, not just all 
	  files in pkgdatadir
	* mdemo/Makefile.am: removed the rule for libltdl configuration
			
1999-01-13  Alexandre Oliva  <[e-mail]>

	* mdemo/Makefile.am (../libltdl/libtool): mkdir and configure
	../libltdl

1999-01-13  Thomas Tanner  <[e-mail]>

	* demo/dlmain.c, libltdl/ltdl.c, ltconfig.in, ltmain.in, 
	  doc/libtool.texi: renamed dld_preloaded_symbols to 
	  lt_preloaded_symbols, symbol lists are 'const'
	* cdemo/configure.in: don't check for string.h
	* demo/dlmain.c: renamed dld_symlist to lt_symlist,
	  preloaded symbols are 'const', use lt_ptr_t instead of void*
	* demo/foo.h: define lt_ptr_t
	* doc/libtool.texi: document lt_preloaded_symbols correctly
	* libltdl/Makefile.am, mdemo/Makefile.am: renamed libtest to libltdlc
	* libltdl/ltdl.c: fixed some minor typos, renamed dldpre to presym,
	  bugfix: search in search_path only if we have no directory 
	  and a search_path, in lt_dlsym() check whether symbol != 0
	* libltdl/ltdl.h: removed lt_dlpreopen_default()
	* ltconfig.in (dlpreopen): removed dld_preloaded_symbol_count
	* ltmain.in: added help for -avoid-versioning, -export-symbols,
	  -module, add @SYMFILE@ if one of -export-dynamic, -dlopen or
	  -dlpreopen is used
	* mail/deplibs.html: added Gordon Matzigkeit's inter-library
	  dependencies article
	* mdemo/Makefile.am: removed -export-dynamic from LDFLAGS
	  (no longer necessary, since libtool defines lt_preloaded_symbols
	  when -dlopen is used), initialize with lt_preloaded_symbols
	
1999-01-13  Alexandre Oliva  <[e-mail]>

	* doc/libtool.texi (Test descriptions): cdemo-static works, thanks 
	to Edouard Parmelan!

	* THANKS: added Sebastian Wilhelmi

	* ltconfig.in (solaris): define `need_version' to no

1999-01-13  Sebastian Wilhelmi  <[e-mail]>

	* ltconfig.in (solaris): Define `deplibs_check_method',
	`file_magic_command', `need_lib_prefix' and `sys_lib_search_path'
	* ltmain.in (file_magic_regex): Add space before matching pattern,
	such that it works on solaris (solaris has a tab between the
	library name (including the colon) and the `ELF' and such the
	`ELF' will never be matched).

1999-01-13  Edouard G. Parmelan  <[e-mail]>

	* ltconfig.in (NM): PATH search was not updated like in
	libtool.m4, in last Alexandre Oliva's change to it
	(sysv4*, ncr): pass all library dependencies
	* ltmain.in (dependency_libs, -R): use `deplib' instead of `arg' to
	iterate, otherwise we'd overwrite `arg'
	(convenience, old_libs): if --disable-shared, convenience
	libraries are just old archives, as .lo's are of no use
	* tests/cdemo-static.test: print --disable-shared here

1999-01-13  Alexandre Oliva  <[e-mail]>

	* libltdl/configure.in (libltdl_cv_shlibext, LTDL_SHLIB_EXT):
	system-dependent extension of shared libraries
	(libltdl_cv_shlibpath_var, LTDL_SHLIBPATH_VAR): system-dependent
	run-time shared library search path
	* libltdl/ltdl.c (dldpre_init, dldpre_exit): unrelate init/exit
	from add/remove symlists, so one may add dld_preloaded_symbols
	from main(), when only a library will call dldpre_init
	(lt_dlopen): use LTDL_SHLIBPATH_VAR, if defined, as secondary
	search path.  Also, if a requested .la file cannot be found, try
	with the LTDL_SHLIB_EXTension instead.

	* ltmain.in (old_archives, oldobjs): use find to SYMDEF here too

	* Makefile.am (@DIST_MAKEFILE_LIST@): `$' must be doubled

	* configure.in (AC_CONFIG_DIRS): configure only libltdl, and then,
	only if --enable-ltdl-install
	(CONF_SUBDIRS): list directories that are configured on demand,
	but that must be included in the distribution
	(ACINCLUDE_M4_LIST, DIST_MAKEFILE_LIST): generated from CONF_SUBDIRS
	* Makefile.am (AUTOMAKE_OPTIONS): added version 1.3e and
	readme-alpha, to handle README-alpha automatically
	(EXTRA_DIST): removed README-alpha
	(BUILD_SUBDIRS): subdirectories that are always built
	(SUBDIRS): BUILD_SUBDIRS plus BUILD_LTDL
	(DIST_SUBDIRS): BUILD_SUBDIRS plus CONF_SUBDIRS, from configure
	(all-local, check-local): depend on $(ACINCLUDE_M4_LIST), from
	configure, and libtool, so that it is built before subdirs
	(configure-subdirs): new target
	(configure-subdirs, distdir): depend on $(DIST_MAKEFILE_LIST),
	from configure
	(@DIST_MAKEFILE_LIST@): create subdir if needed, then run
	configure.
	On-demand configuration of subdirs at distribution time was
	suggested by Gary V. Vaughan <[e-mail]>

	* libtool.m4, ltconfig.in (NM): search for NM in PATH before
	/usr/ccs/bin, /usr/ucb and /bin.  However, if the found one isn't
	BSD-compat keep searching.  If no BSD-compat is found, use the
	first we found.

	* THANKS: added Raffaele Sena

1999-01-13  Raffaele Sena  <[e-mail]>

	* libltdl/ltdl.c: replaced RTDL with RTLD

1999-01-13  Manish Singh  <[e-mail]>

	* ltconfig.in (osf3*, osf4*, irix6*): include
	${libname}{release}.so for library_names_spec

1999-01-13  Alexandre Oliva  <[e-mail]>

	* configure.in (AC_CONFIG_SUBDIRS): added cdemo
	* Makefile.am (DIST_SUBDIRS): ditto
	(ACINCLUDE_M4_LIST): ditto
	* tests/Makefile.am (TESTS): added cdemo-shared.test
	* tests/cdemo-static.test: disable shared libraries here
	* tests/cdemo-shared.test: disable static libraries here
	* doc/libtool.texi (Test descriptions): added cdemo tests
	* THANKS: added Edouard G. Parmelan

1999-01-13  Edouard G. Parmelan  <[e-mail]>

	* ltmain.in: fix convenience libraries when static libraries
	are disables.
	* cdemo/README, cdemo/Makefile.am, cdemo/configure.in, cdemo/foo.h,
	cdemo/foo1.c, cdemo/main.c, cdemo/.cvsignore, test/cdemo-conf.test,
	test/cdemo-make.test, test/cdemo-exec.test, test/cdemo-static.test:
	new tests for convenience libraries.
	* autogen, Makefile.am, test/Makefile.am: ditto.

	* ltconfig.in, doc/PLATFORMS: Added support for NCR MP-RAS
	(i586-ncr-sysv4.3*) with native compiler.
	* README, doc/libtool.texi: Added note for NCR MP-RAS compiler.

1999-01-12  Thomas Tanner  <[e-mail]>

	* ltmain.in: before using LN_S remove the symlink
	* libltdl/ltdl.c: support multiple symbol lists, moved library-
	  and file searching to separate functions, renamed "preload_libs"
	  to "dl_dependency_libs", set the LT_SYMBOL_OVERHEAD to the correct
	  value (7), fix to support lt_dlsym() for not-libtool modules again,
	  check for invalid handles, when using strdup() check whether
	  it fails
	* libltdl/ltdl.h: declare the lt_dlsymlist type for lt_dlpreopen()
	* mdemo/README: rewritten
	* mdemo/configure.in: check only for math.h (string.h is no longer
	  necessary)

1999-01-12  Gary V. Vaughan  <[e-mail]>

	* configure.in (ltdl-install): Fixed up the indentation so that
	`configure --help' is pretty again.

1999-01-11  Alexandre Oliva  <[e-mail]>

	* ltmain.in, NEWS, doc/libtool.texi: Added support for -R flag
	* ltmain.in, doc/libtool.texi: documented that -rpath is the same
	as -R for programs
	* ltmain.in: softened the instructions for linking with installed
	libraries, and noted that libtool can be used to link with them;
	documented that -rpath is not required for convenience libraries

	* ltconfig.in (symxfrm): don't print $pipe_works twice, once for
	each $ac_symprfx
	Reported by Godmar Back <[e-mail]>

	* ltmain.in (convenience, libobjs): get only .o and .lo files from 
	the files extract from the convenience library.  Some systems,
	such as FreeBSD2, will add a SYMDEF file, that is not an object
	file, and therefore should not be fed to the linker

	* libtool.m4 (AM_SYS_NM_PARSE): while we are at it, we may well
	cache the value of ac_cv_sys_symbol_underscore

	* libtool.m4 (AM_SYS_NM_PARSE): need for underscore prefix is now
	auto-detected, by trying first without, then with it.  
	
	* ltconfig.in: ditto

1999-01-10  Alexandre Oliva  <[e-mail]>

	* configure.in (AC_CONFIG_SUBDIRS): add libltdl, demo, mdemo and
	depdemo commented out, so that `dist' works before `check'
	(BUILD_LTDL): will contain libltdl if --enable-ltdl-install
	* Makefile.am (DIST_SUBDIRS): expand SUBDIRS and add depdemo,
	commented out
	(SUBDIRS): add $(BUILT_LTDL)
	* libltdl/Makefile.am (EXTRA_LTLIBRARIES): add libtest.la, the
	same as libltdl but always a convenience library.  Not built by
	default.  Both libraries now depend on the libtool script, that
	depends on ../libtool and is rebuilt when needed
	* mdemo/Makefile.am (mdemo, mdemo.debug): depend on and link with
	../libltdl/libtest.la, that is rebuilt if needed
	(mdemo_LDADD): removed $(LIBADD_M), to avoid silent failures
	(foo1.la): renamed from libfoo1.la; test removing the lib prefix
	* mdemo/foo1.c: renamed libfoo1_LTX symbols to foo1_LTX
	* mdemo/main.c: don't include string.h nor math.h, nor refer to
	sin nor cos
	* tests/mdemo-exec.test: renamed libfoo1.la to foo1.la
	* tests/mdemo-inst.test: ditto

	* libltdl/ltdl.c (FILENAME_MAX): use it instead of MAX_FILENAME,
	and don't redefine it if already defined; default to 1024, as on
	most systems
	(LT_SYMBOL_LENGTH): renamed from MAX_SYMBOL_LENGTH
	(LT_SYMBOL_OVERHEAD): new macro, that accounts for the size of
	the _LTX_ separator and the initial underscore
	(lt_dlsym): sym now points to a stack buffer (lsym) if possible,
	or is dynamically allocated.  If allocation fails, a
	buffer_overflow_error is returned.

1999-01-10  Thomas Tanner  <[e-mail]>

	* ltmain.in: define dld_preloaded_symbols if at least one of
	  -export-dynamic, -dlopen or -dlpreopen was specified,
	  do not include program objects in the symbol list
	  if -export-dyn
