	* configure.in (GTK_EXTRA_CFLAGS): Include the -mms-bitfields flag
	in GTK_EXTRA_CFLAGS on Win32, so that it gets included in the
	gtk+-2.0.pc file and automatically used by dependents. MSVC users
	who use pkg-config will have to manually edit it out from
	gtk+-2.0.pc, sorry. Maybe pkg-config should be enhanced to support
	some kind of conditionals in .pc files?
