The patch I posted compiled and ran fine.
I tested the speed with a file that called the function or macro 64^3 
(262144) times.
The macro version used 238 seconds, and the function version used 208 
seconds, so the function version takes about 87% as long as the macro.

It seems macros don't have that much overhead...at least, the MegaPOV 
macros, which have been optimized. However, in a collision detection 
algorithm, which could easily use even more calls, this small 
improvement would still be helpful.
