The C front end already emits generic, so there's almost no win in
rewriting it (one lame tree code in c-common.def -- not worth the
effort ;-).
I was thinking to rewrite the C++ front-end not to use extra tree
codes you would also need to rewrite the C front-end but now thinking
about, you could use one tree code for all of C++ and then use
subcodes or at least one tree code for types, one for expressions, one
for decls and one for all others and then use subcodes. This seems
more like good an inherience issue, right now we have a very flat
class system, this change will then making it slightly higher
inheianct chain but we should able to reduce some of the bloat from
the middle-end that the C++ front-end abuses the tree structure wise.
