* libtool.m4 (export_symbols): On Windows, if the export_symbols
file (which has been passed to libtool with the -export-symbols
command line switch) already is a .def file, use it as is.

the application the new MT API.

multi-threaded calls into libltdl.
(lt_dl_mutex_lock): Type of a locking callback function.
(lt_dl_mutex_lock): Type of an unlocking callback function.

the last saved error message from thread local storage.
don't sweat -- it may be a lib that is already statically linked
into the loading application.
* libltdl/ltdl.c: Clean up the shadowing of the global handles
variable.
(LT_DLRESIDENT_FLAGS): Add extra parens to satisfy -Wall.
(load_deplibs): Cast isspace() argument to an int to satisfy

* ltdl.c (lt_caller_data): New type.
(lt_dl_handle_struct): Add an lt_caller_data field.
(lt_dlcaller_register, lt_dlcaller_set_data,
lt_dlcaller_get_data): New functions.
(rpl_memcpy): A minimal fallback implementation.
(rpl_realloc): A realloc implemented with lt_dlmalloc and
lt_dlfree.
(LT_DLMALLOC, LT_DLFREE, LT_DLREALLOC, LT_DLMEM_REASSIGN):
New memory handling convenience macros. Use them
appropriately throughout the rest of this file.
* ltdl.h (lt_dlcaller_register, lt_dlcaller_set_data,
lt_dlcaller_get_data): Prototyped.
* doc/fdl.texi (GNU Free Documentation License): contained @bye
command which prevented part of document to be generated (indices,
etc).
* doc/libtool.texi (Dlpreopening): the @deftypevar did not contain
a space after a type.
below can detect preopened library deplibs correctly in libltdl,
we need to ensure that libtool library deplibs are also preloaded
into the binary for that phase to work.
out ac_cv_global_symbol_to_cdecl inside the loop, incase we
need to go around again and try with underscore prefix.
(_LT_AC_TRY_DLOPEN_SELF): On some hosts (cygwin for instance)
self dlclosing unloads the main program and causes a SIGSEGV. So
don't do it for now.
way. This should fix it some:
* libtool.m4 (extract_expsyms_cmds): There is a quoting problem
with autoconf-2.13 that prevents [$]0 from expanding. Use shell
quotes instead to delay eval of $0.
(impgen.c) The '# ' sequence stripped by sed works again.
* libltdl/ltdl.h (lt_dlmakeresident, lt_dlisresident): Add
prototypes.
(LT_DLERROR_CLOSE_RESIDENT_MODULE): New error status.
* libltdl/ltdl.c (lt_dlmakeresident, lt_dlisresident): Allow
making and testing of resident module status, which prevents a
module from being lt_dlclosed.
(lt_dlopen): If lt_dlopen()ing self, make the module resident.
(lt_dlclose): Return an error if the module is resident.

(AC_LTDL_DLOPEN_SELF): ...to here.
(_LTDL_AC_CHECK_DLFCN): Factor out repeated code for dlfcn.h
(_LT_AC_TRY_DLOPEN_SELF): Factor out repeated code for
checking dlopen status.
* ltdl.m4 (AC_LIB_LTDL): Use _LTDL_AC_CHECK_DLFCN.
dlopen compile time checking. Use _LTDL_AC_CHECK_DLFCN.
(AC_LTDL_DLSYM_USCORE): Use _LTDL_AC_TRY_DLOPEN_SELF.
for modules. If the named module has no directory component,
always start the search with the user_search_path directories,
and then fall back on the current directory only if that fails.

* doc/libtool.texi (Libltdl interface): Document
LT_NON_POSIX_NAMESPACE.
* libltdl/ltdl.h (LT_POSIX_NAMESPACE): Deleted. The default is
now to use this namespace, so the cpp macro is no longer
necessary.
