non-i386, non-unix, and generatable files have been trimmed, but can easily be added in later if needed. gcc-2.7.2.1 will follow shortly, it's a very small delta to this and it's handy to have both available for reference for such little cost. The freebsd-specific changes will then be committed, and once the dust has settled, the bmakefiles will be committed to use this code.

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