* ltconfig.in, ltmain.in: updated and fixed the patches below
1998-11-04 Thomas Tanner <tanner@gmx.de>
* mdemo/*: added new demo to demonstrate building of dlopenend
modules
* tests/Makefile.am, tests/mdemo*: added some tests for mdemo
1998-11-04 Gary V. Vaughan <gvaughan@oranda.demon.co.uk>
* demo/configure.in: added AC_EXEEXT macro so that the tests can
work on cywin32/mingw32 hosts. This requires the current CVS
autoconf
1998-11-04 Thomas Tanner <tanner@gmx.de>
* ltmain.in: New flag -export-symbols; new dlpreopen system
* demo/dlmain.c: removed dld_preloaded_symbol_count
1998-11-04 Ian Lance Taylor <ian@cygnus.com>
* ltmain.in: On installation, don't get confused if the same name
appears more than once in the list of library names.
1998-11-04 Ian Lance Taylor <ian@cygnus.com>
* ltconfig.in: Add objext and libext variables. Check for object
suffix. Check for mingw32* as well as cygwin32*. Use objext when
testing compiler. Add support for Visual C++ on cygwin32 when not
using gcc. Add objext, libext, and fix_srcfile_path to generated
libtool script.
* ltmain.in: Use .${objext} rather than .o. Use fix_srcfile_path
if it is set. Check for .obj as well as for .o, and for .lib as
well as for .a. Use .${libext} rather than .a when creating old
libraries.
* libtoolize.in: Change initial /bin/sh to @SHELL@.
* libtool.m4 (AM_PROG_LIBTOOL): Add AC_REQUIRE for
AC_CANONICAL_BUILD, so that autoconf doesn't get mixed up by the
AC_REQUIRE in AC_CHECK_TOOL.
1998-11-04 Ian Lance Taylor <ian@cygnus.com>
* ltconfig.in: Look in the right directory for libtool.c in
archive_cmds for cygwin32.
1998-11-04 Ian Lance Taylor <ian@cygnus.com>
* ltconfig.in: Fix cygwin32 support to avoid using a double
extension, to delete the def file, to set version_type to windows,
and to include versuffix in the DLL name.
* ltmain.in: Add support for a version_type of windows.
1998-11-04 Ian Lance Taylor <ian@cygnus.com>
* ltconfig.in: Add cygwin32 support.
* libtool.m4 (AM_PROG_LIBTOOL): Call AM_SYS_LIBTOOL_CYGWIN32 on a
cygwin32 host. Pass DLLTOOL and AS to ltconfig.
(AM_SYS_LIBTOOL_CYGWIN32): New macro.
