30#  ??????  fixup comment
31#	This script munges the native include files provided with Windows NT
32#	3.5 SDK systems so as to provide a reasonable namespace when
33#	compiling with gcc.  The header files by default do not
34#	provide many essential definitions and declarations if
35#	__STDC__ is 1.  This script modifies the header files to check
36#	for __STRICT_ANSI__ being defined instead.  Once munged, the
37#	resulting new system include files are placed in a directory
38#	that GNU C will search *before* searching the Include
39#	directory.
40#
41#	See README-fixinc for more information.
