Subject: Need Common Lisp-compatible transcendental functions

I'm implementing a run-time system for Lisp-like languages in C++,
and I need Common Lisp-compatible transcendental functions:
sin, cons, log, etc for complex arguments. Any suggestions?

Also, does anyone have suggestions for how to treat infinities?
My model is that: +Infinity == +1/0 and -Infinity == -1/0.
Is this reasonable? How about complex numbers?
Any references to designs worked out by someone
with a strong math background?

My system contains GNU code, so I need code that is compatible
with the GNU license. (Kcl isn't.)

I will summarize mail.
