  26 #       This script munges the native include files provided with Windows NT
  27 #       3.5 SDK systems so as to provide a reasonable namespace when
  28 #       compiling with gcc.  The header files by default do not
  29 #       provide many essential definitions and declarations if
  30 #       __STDC__ is 1.  This script modifies the header files to check
  31 #       for __STRICT_ANSI__ being defined instead.  Once munged, the
  32 #       resulting new system include files are placed in a directory
  33 #       that GNU C will search *before* searching the Include
  34 #       directory.
  35 #
  36 #       See README-fixinc for more information.
