I think the last we left it, we wanted documentation for the manual, and
for this to work for Obj-C and C++ too (I don't see why it should be C
only).  Other than that, it looks OK.  It does not apply cleanly to 3.1
though.

If you update it to fix the above issues and no-one has any objections
(Zack?) then I'll do my best to see it gets applied for 3.1.

However, I'm not sure whether this will work for 3.2.  I want the
separate preprocessor to die completely in 3.2, but I'll try to retain
your semantics if possible by passing it through cc1 twice, I guess.
