25: # This script munges the native include files provided with SCO
26: # 3.2v4 systems so as to provide a reasonable namespace when
27: # compiling with gcc. The header files by default do not
28: # provide many essential definitions and declarations if
29: # __STDC__ is 1. This script modifies the header files to check
30: # for __STRICT_ANSI__ being defined instead. Once munged, the
31: # resulting new system include files are placed in a directory
32: # that GNU C will search *before* searching the /usr/include
33: # directory. This script should work properly for most SCO
34: # 3.2v4 systems. For other types of systems, you should use the
35: # `fixincludes' or the `fixinc.svr4' script instead.
