+# 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.
