What sort of processor are you using and what sort of timing
constraints do you have? You may find that the time taken to perform
the function call (even a lot of them) isn't as much as you would
think. This is especially true if porting from, for example, a 68020
to a PPC740.
In some cases, including function/procedure calls, instead of inlining
the equivilant code and speed you app up (by avoid cache misses).
