New Revision: 1613
URL: http://svn.gnome.org/viewvc/gnomemm?rev=1613&view=rev

Log:
2007-07-20  Armin Burgmeier  <armin openismus com>

	* configure.in: Added detection of Win32 platform, and added the
	AC_LIBTOOL_WIN32_DLL macro to produce a DLL on Windows.

	* build_shared/Makefile_build.am_fragment: Add -no-undefined to the
	ldflags on Windows because DLLs are not allowed to contain undefined
	references.
