# 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.
