I'd like to be able to utilize functions that are not internally available in
POV (Gamma functions, Bessel functions, things like that) and wondered if there
was a way to "include" files like that.

I can try my hand at rewriting them in SDL, but I didn't know if there was a way
to pass something to / call a C "subroutine" and have it return something to POV
for use in the scene.

One of the functions had some yucky goto's and given the usual lack of round
tuits and my lack of recent experience in reading / writing C, I didn't feel
like unravelling that sort of programming.

Thanks

Short of compiling it into POV-Ray's binary? Nope.
