  24 #       This script munges the native include files provided with System V
  25 #       Release 4 systems so as to remove things which are violations of the
  26 #       ANSI C standard.  Once munged, the resulting new system include files
  27 #       are placed in a directory that GNU C will search *before* searching
  28 #       the /usr/include directory. This script should work properly for most
  29 #       System V Release 4 systems.  For other types of systems, you should
  30 #       use the `fixincludes' script instead.
