#  ??????  fixup comment
#	This script munges the native include files provided with Windows NT
#	3.5 SDK systems so as to provide a reasonable namespace when
#	compiling with gcc.  The header files by default do not
#	provide many essential definitions and declarations if
#	__STDC__ is 1.  This script modifies the header files to check
#	for __STRICT_ANSI__ being defined instead.  Once munged, the
#	resulting new system include files are placed in a directory
#	that GNU C will search *before* searching the Include
#	directory.
#
#	See README-fixinc for more information.
