Hi, Eli!

I just noticed this one in a Usenet spool.  I don't seem to be
subscribed to bug-gnu-emacs (I thought I was) at the moment, and
nothing got forwarded to me.

Recompile in this order:
(i) cc-defs.el (if necesaary); this file contains mostly macros.
(ii) cc-langs.el (..); this contains "language variables", those whose
  values differ between C, C++, ....., AWK.
(iii) cc-engine.el and cc-mode.el (uses macros generated in (i) and
  (ii)).

I tried to do this some while back, but got bogged down in the
complixities of make.
