At long last I am sending out a fix for the problem with CPP
that I reported last month.  The delay is because of some
unbelievable disk problems I will report later.  Thanks for
your help.

Subject: Change to C preprocessor source
To: lou

Here are the changes to the C preprocessor source dated 83/03/30, no SCCS
identification, modified by Reiser@???.
The source file is "/usr/src/cmd/cpp/cpp.c".
The following changes can be applied by putting the following commands
in a file and executing them in the directory /usr/src/cmd/cpp.
The old version of cpp.c will be copied into the file cpp.c.old,
and will always be available as revision 2.1 from s.cpp.c.
These commands will install /lib/cpp according to the Makefile in the source
directory.
If you do not have SCCS, the line containing %W% %G% should be changed so that
those two strings read instead as "@(#) cpp.c	2.1.1.1 8/9/83".
