libtool installs/uninstalls the import library, no need to do it

2005-06-26  Tor Lillqvist  <tml@novell.com>

	* glib/Makefile.am: libtool installs/uninstalls the import
	library, no need to do it ourselves. Do still install/uninstall
	the .def file, though.

	* glib/gmappedfile.c: Add Win32 implementation.
	(g_mapped_file_free): Don't mention writable shared mappings in
	the doc comment. Free the GMappedFile struct.

	* tests/mapping-test.c (main): No kill() or SIGUSR1 on Win32, use
	a flag file instead to stop the child. Use g_usleep() instead of
	sleep().
