will be used as an argument for $file_magic_cmd to test whether
the regex in deplibs_check_method matches its output
(file_magic_cmd): use full pathnames whenever possible
lists the system *run-time* search path. Listed directories are
not implicitly hard-coded into executables.
* ltmain.in: use it, but *never* discard -R flags
* doc/libtool.texi: document it
* NEWS: ditto

output of NM too
(global_symbol_to_cdecl): new variable; convert the output of
global_symbol_pipe to valid C declarations; on HP/UX, convert
text symbols to function declarations
* libtool.m4: similar modifications
* doc/libtool.texi: document new variable
* ltmain.in: use global_symbol_to_cdecl to generate lt_dlpreopened
symbols; avoid extracting symbol lists from dlpreopened files
twice; do not filter symbols from dlpreopened libraries
* TODO: fixed HP/UX dlpreopening problem
(AC_LIBTOOL_SETUP): if lt_dlopen=yes, add --enable-dlopen to
libtool_flags; drop --enable-dlopen-self
* ltconfig.in: perform all the dirty work of testing for dlopening
support, because we need platform-dependent equivalents for
-export-dynamic, for self dlopening, and -static, for static self
dlopening
(dlopen_self_static): new configuration variable that is set to
yes only if static programs can dlopen themselves
* ltmain.in (-static, -all-static): dlopen_self=dlopen_self_static
configure-work that AC_PROG_LIBTOOL used to do; add
--cache-file=$cache_file to libtool_flags
(AC_PROG_LIBTOOL): call AC_LIBTOOL_SETUP, save the cache, run
ltconfig and reload the cache
* configure.in: run AC_LIBTOOL_SETUP, then set LIBTOOL_FLAGS to
libtool_flags
* ltconfig.in: support --cache-file switch. If it is used, load
the cache in the beginning and save it just before terminating
need relink; in the other cases, set it to needless
* ltmain.in (fast_install): if needless, set relink_command empty
* doc/libtool.texi (fast_install, shlibpath_overrides_runpath):
document the new behavior
* demo/configure.in: use AC_LIBTOOL_DLOPEN
* libtool.m4: added AC_ENABLE/DISABLE_FAST_INSTALL macro
* ltconfig.in: added --disable-fast-install flag
* ltmain.in: partially reverted Alexandre's patch and implemented
on-demand linking in such a way that the old developer-friendly
linking style is optional,
don't hardcode library paths that are in the system search path,
fixed a typo in lib_search_path,
implemented -export-symbols-regex for programs
the next version of cygwin.
(sub_uncdir): removed. We use <drive>:/path/to/executable now.
* libtool.m4 (AC_PROG_LD): removed sub_uncdrive and sub_uncdir.
determines whether LD_LIBRARY_PATH or equivalent can be used to
override a hard-coded library search path; default to unknown
(linux-gnu*): set it to no
(solaris*, sunos4*): set it to yes
* ltmain.in (build_libdirs_flags, build_libdirs, build_rpath): if
shlibpath_overrides_runpath is not yes, arrange that wrapper
scripts create, on demand, programs that use uninstalled libraries
* doc/libtool.texi: document it
export_symbols_cmd.
(cygwin, mingw): Be sure to compile the ltdll.c object before
extracting the exported symbol list. Extract only the names
of the exported symbols from the def file [otherwise we might
run into trouble with -export-symbols-regex].
(archive_expsym_cmds): Regenerate the def file from the symbol
export list.
(delay_variable_subst): New sed expression to allow us to delay
evaluation of $foo in a double_quote_subst evaluated variable by
using $.
* ltmain.in (export_symbols_cmds): evaluate each ~ delimitted cmd
separately.
* doc/libtool.texi (libtool script contents): new paragraph to
explain the difference between _cmd and _cmds suffixes for
variable names.
(export_symbols_cmds): renamed from export_symbols_cmd.
re-export the dll entry points DllMain@12, _cygwin_dll_entry@12 and
_cygwin_noncygwin_dll_entry@12 to avoid bugs with the wrong entry
function being called with inter-dll dependencies.

* THANKS: Added DJ Delorie, since his code inspired the impgen.c
program and because he has patiently answered all of the
irritating dll and win32 questions I have fired at him.
* autogen: only libltdl needs autoheader
* doc/libtool.texi (link mode): documented -export-symbols-regex
and updated -export-symbols

always_export_symbols, export_symbols_cmd, exclude_expsyms,
include_expsyms, dlopen and dlopen_self
more detailed description of need_lib_prefix

of export_symbols_cmd
* ltmain.in: implemented -export-symbols-regex
* cdemo/foo1.c: renamed to foo.c

fixed bug for filename == 0
* libltdl/ltdl.h: use __P macro for lt_dlmalloc/free
* libtool.m4: new macro AC_LIBTOOL_DLOPEN: checks for dlopen
and dlopen(NULL) support

--enable-dlopen[-self] flags for AC_LIBTOOL_DLOPEN
* ltmain.in: use dlopen[_self], dlpreopen files if there's no
dlopen support, build lt_preloaded_symbols only if
-dl[pre]open was used, include program symbols if -export-dynamic
was specified and there's no dlopen(NULL) support
* mdemo/configure.in: use AC_LIBTOOL_DLOPEN
* mdemo/main.c: demonstrate lt_dlopen(0)
* *demo/configure.in: use AC_CHECK_LIBM

(returns a handle for the program itself)
* ltconfig.in: minor reformatting
* ltmain.in: in lt_preloaded_symbols always define
the program's symbols first, for -export-dynamic list all
program symbols together, -export-symbols was broken for
programs, minor reformatting
* mdemo/Makefile.am: renamed mdemo.debug to mdemo.static
* tests/mdemo*: ditto, mdemo.test was completely broken
-set_version in archive_cmds if verstring is empty
(irix6*, shlibpath_var, sys_lib_search_path-spec,
deplibs_check_method): set appropriate values depending on
selected ABI, -32, -n32 or -64, as set in LD by libtool.m4
(uts4*): remove dot between .so and versuffix
colon, because on IRIX 5 only the last -rpath switch prevails, and
it can be a list of colon-separated directories. This change will
affect irix6 too, but that's not a problem.
addition to space as separator, and allow more than one space
between the symbol code and the symbol name; HP/UX's nm, for
example, uses two spaces
* ltconfig.in (global_symbol_pipe): ditto
(bsdi4, deplibs_check_method): variable name was misspelled
* libltdl/configure.in (libltdl_cv_preloaded_symbols): rewrite
test, so as not to depend on the way global_symbol_pipe is
initialized; the current test would get false positives, as
global_symbol_pipe was initialized `x=""', not `x='
*-*-cygwin32. sed -e 's%(cygwin|mingw)32%1%g' ltconfig.in
* ltmain.in: sed -e 's%(cygwin|mingw)32%1%g' ltmain.in
* ltconfig.in (hardcode_libdir_flag_spec, allow_undefined_flag,
archive_cmds, archive_sym_cmds, old_archive_from_new_cmds):
removed duplication of config by assuming that `test $with_gcc =
yes' implies gnu ld, otherwise MSVC++ (which I haven't tested
since I inheritted the code from Ian Lance Taylor btw!) is implied.
* demo/configure.in: likewise
* depdemo/configure.in: likewise
* libltdl/configure.in: likewise
* mdemo/configure.in: likewise
* libltdl/ltdl.c: in find_module() check whether libdir is defined,
tryall_dlopen(): move deallocation of an already opened handle
to lt_dlopen(), allocate the directory in lt_dlopen() dynamically,
minor cleanups, fixed memory leak (name)
* libtool.m4: renamed all AM_ macros to AC_ and added aliases for
compatibilty, updated AC_SYS_NM_PARSE (no undefined symbols,
don't count the symbols)

added generic variable for linker options "linkopts" in
all archive_cmds
* ltmain.in: added -thread-safe flag (unused)
more general regular expressions
(file_regex): remove it; the name is misleading, it's not used
* ltconfig.in, doc/libtool.texi: ditto
* ltconfig.in (linux-gnu*, deplibs_check_method): extend regex to
support `LSB dynamic lib' in the output of `file'
Reported by Scott D. Heavner <sdh@po.cwru.edu>
added function lt_dlopenext(), removed reference to
LTDL_PRELOADED_SYMBOLS in LTDL_SET_PRELOADED_SYMBOLS
* libltdl/ltdl.c: partially reverted Alexandre's dynamic string
allocation change (it was not necessary and the code was unreadable),
cleanups, removed usr_search_path_size, renamed usr_search_path
to user_search_path, in find_module() also check for moved
modules, merged find_file() and find_library(),
added lt_dlopenext(), in lt_dladdsearchdir() no longer reset
the search path if 'search_dir' == NULL and don't use realloc()
(might not be available on all platforms),
removed __P((void)) in the declaration of lt_dlgetsearchpath()
* libltdl/ltdl.h: added lt_dlopenext()
* ltconfig.in: AIX archive commands were broken,
fixed a MAJOR bug in global_symbol_pipe which caused
"demo-shared.test;demo-make.test" to fail (libtool must not extract
undefined symbols of libraries, i.e. symcode must not contain 'U')
* tests/Makefile.am (clean-local): "make distclean" in cdemo, too
