Cproto coming with RedHat 5.8.6 has the following problems:

1. It is old - there is a newer version (4.6)

2. It coredumps on some files I'm processing - there is
a       bug in it (new version including) that I've fixed.

3. It's compile-time limits for number of nested #include
   levels is too low - my fellow co-worker Oleg
Goldshmidt      made a patch for that.

I'll put to the gribble uploads two things:

cproto-4.6.tar.gz
cproto-4.6.1-patch - a patch to 4.6.1 which fixes both
problems above.
