I'm wondering why there is seems to be no ANSI-C to C compiler around,
a la "cfront", the C++ to C compiler. It would seem to be a natural.
There are a couple of things that would have to be kluged up a little --
passing floats rather than doubles as parameters, for example -- but
that's no big deal.

Is there a market for such a beast? Is there one available? If not,
I'm sure I could rig one up without too much trouble.
