First, you should beat on Convergent, since real SVR2 had flexnames.

It's not hard to modify cpp to support long names (the one I shipped
as part of the BRL UNIX System V Release 1.0 emulation for 4.2BSD
was so modified), but you need the source, and it will only help map
symbols that you introduce explicit #defines for.  You might be better
off making the necessary changes with a good text editor.
