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.
