wconfig.c: Updated to be more featureful. It will now save the

	arguments passed to it and emit it as a makefile variable
	WCONFIG_FLAGS.  This allows the makefile to be able to preserve
	wconfig options in the future when updating makefile.  Also added the
	--win32 and --win16 options to force win16 or win32 makefiles.  An
	option of the form --enable-foo will cause lines that begin ##FOO## to
	be uncommented in the Makefile.  The program has also been cleaned up
	so it can be run (for debugging purposes) under Unix.
