I think maybe all anyone really needs is the equivalent of pinvoke, then
they can do it themselves.
Is there a library that allows me to dynamically call a C function
without generating code? Ie, if I know it has an int as the first
argument, and a char * as the second, can I dynamically call it? I think
if there is, then there is no reason that gcj can't be at least as
compatible to C as Mono is alleged to be.

If you had a library that could call C functions then surely you could
just use JNI to attach to it, thus making everybody happy?
