26: # This script munges the native include files provided with SCO
27: # 3.2v4 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 /usr/include
34: # directory. This script should work properly for most SCO
35: # 3.2v4 systems. For other types of systems, you should use the
