modify gccxml to use the c front end (and obviously output the correct

well?
Most of the effort for gccxml went into the support for processing the
headers of each native compiler. This would not have to be repeated to
support C.
The actual dump code for the C++ front-end is in GCC/gcc/cp/xml.c under
the gccxml source tree. There is a hook in the finish_translation_unit
function in the semantics.c file that invokes the dump. Creating a C
dump would mean creating a GCC/gcc/xml.c file and putting a hook in the
C front-end. I'm not sure how much of the dump code could be shared
between the two files.
I am not an expert, but from what I have researched I understand that
the gcc c and c++ compilers share the same source representations
('Trees'), so one would think that much of the code would be reused.
Much of the representation is shared. The C++ compiler adds a bunch of
tree node types.
