Yes, that's another part of the problemn indeed.  My suggestion just removes
the need to compile cc-langs.el before compiling cc-engine.el but doesn't
help making sure that cc-engine.el gets recompiled at all.

This requires something in the Makefile, but we could extract it
(semi-)automatically by doing a makedepend kind of thing (I had written such
a trick which looks for `require's and `provide's to build the dependencies:
it does suffer from circular dependencies, so either we'd have to live with
complaints from `make' or we'd have to break those dependencies manually).
We could also tweak the byte-compiler to do something like what
"gcc -MD" does, but I suspect this would also suffer from
circular dependencies.
