  28 #       This script munges the native include files provided with SCO
  29 #       3.2v4 systems so as to provide a reasonable namespace when
  30 #       compiling with gcc.  The header files by default do not
  31 #       provide many essential definitions and declarations if
  32 #       __STDC__ is 1.  This script modifies the header files to check
  33 #       for __STRICT_ANSI__ being defined instead.  Once munged, the
  34 #       resulting new system include files are placed in a directory
  35 #       that GNU C will search *before* searching the /usr/include
  36 #       directory.  This script should work properly for most SCO
  37 #       3.2v4 systems.  For other types of systems, you should use the
  38 #       `fixincludes' or the `fixinc.svr4' script instead.
