As far as I can see, the problem is that header files (such as cp/parser.h)
generate GC stuff that gets put into gtype-{lang}.h, where {lang} is determined
by looking at the directory where the file is (eg, if it's in the cp/ directory,
then {lang} is cp) ... unless you override this with a custom hardcoded rule in
gengtype.c.

It seems that all files that are shared between ObjC or C++ and ObjC++ have 
custom
hardcoded rules in gengtype.c.  The cp/parser.h file you added didn't, and 
without
it, every time it is processed, the results are stored in gtype-cp.h even if the
file is processed for ObjC++. :-(

This all looks ugly.  Anyhow, until someone refactors everything, the following
patch fixes ObjC++ bootstrap in trunk by processing cp/parser.h in the same way
as the other C++ headers are processed. :-)

Ok to commit ?

Thanks
