Import of unmodified (but trimmed) gcc-2.7.2. The bigger parts of the

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.

+# NAME:
+#	fixcpp - fix CPP errors
+#
+# SYNOPSIS:
+#	fixcpp [-c][-p patch_file][-b bak_dir][-n new_dir] files(s)
+#
+# DESCRIPTION:
+#	For each named file, use sed(1) to fixup any descriptive
+#	text after #else or #endif or that is not properly
+#	commented as this causes ANSI compilers to generate
+#	unnecessary warnings.
+#
+#	Naturally this script is not guaranteed to be bullet
+#	proof, use of -n or -b is advisable!
+#
+#	-c causes fixcpp to make sure that only files that
+#	needed changing are affected by returning the original
+#	file to its original location if no changes were needed.
+#
+#	-p causes fixcpp to append to a patch file the context
+#	diffs of the changes wrought.
+#
+# SEE ALSO:
+#	sed(1)
