  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.
