	* libtool.m4 (AC_LIBTOOL_SYS_GLOBAL_SYMBOL_PIPE): Don't empty
	out ac_cv_global_symbol_to_cdecl inside the loop, incase we
	need to go around again and try with underscore prefix.

	don't do it for now.

2000-12-05  Gary V. Vaughan  <[e-mail]>

	Oh My! Cygwin support has bitrotted while I was looking the other
	way.  This should fix it some:

	with autoconf-2.13 that prevents [$]0 from expanding.  Use shell
	quotes instead to delay eval of $0.

2000-12-01  Gary V. Vaughan  <[e-mail]>

	dlopen compile time checking.  Use _LT_AC_CHECK_DLFCN.
	(AC_LTDL_DLSYM_USCORE):  Use _LT_AC_TRY_DLOPEN_SELF.

2000-11-29  Gary V. Vaughan  <[e-mail]>

2000-11-25  Gary V. Vaughan  <[e-mail]>

	* libltdl/ltdl.c (lt_dlopen):  Change the default search order

	necessary.

2000-11-20  Morten Eriksen  <[e-mail]>

	* ltdl.m4 (AC_LIB_LTDL, AC_LTDL_SYMBOL_USCORE): Break a circular
	dependency between AC_LTDL_SYMBOL_USCORE and AC_LTDL_DLSYM_USCORE.

2000-11-20  Paul Berrevoets  <[e-mail]>

	regexp fails to match.

2000-11-19  Paul Berrevoets  <[e-mail]>

	* libtool.m4 (_LT_AC_LTCONFIG_HACK): Quote the $ in $#, $2 and
	$3 in variable 'archive_expsym_cmds' for cygwin.

2000-11-19  Gary V. Vaughan  <[e-mail]>

	* ltdl.c: Relegate non-POSIX-compliant symbols (e.g. those
	ending in ``_t'') to deprecated #define compatibility macros.
	Also ease up on the namespace pollution, so that only ``lt_''
	and ``LT_'' prefixes are taken from the global namespace.
	* ltdl.h: ditto.

2000-11-17  Gary V. Vaughan  <[e-mail]>

	* ltdl.c: Reformatted.
	* ltdl.h: ditto.

	libtool manual.
	* doc/libtool.texi: Reference the new license.

2000-10-31  Morten Eriksen  <[e-mail]>

	* libtool.m4 (_LT_AC_LTCONFIG_HACK): Quote argument to avoid
	error output from cygpath when $srcdir is empty.

2000-10-31  Gary V. Vaughan  <[e-mail]>

	* bootstrap:  rm Makefiles to prevent infinite loop during
	configure when libtool.m4 is newer than Makefile.

2000-10-31  Akim Demaille  <[e-mail]>

	* libtool.m4: Adjust the copyright notice.
	Quote all the macro names when defined.
	Some minor formatting changes.
	(AM_PROG_LIBTOOL, AM_ENABLE_SHARED, AM_ENABLE_STATIC)
	(AM_DISABLE_SHARED, AM_DISABLE_STATIC, AM_PROG_LD, AM_PROG_NM):
	Don't use indir when useless.  Don't add trailing `dnl' either.

	* doc/libtool.texi:  Corrected another attack of CRLF line
	endings.
