>> A while back, some of us did some tests, and they revealed that any #DEFINE (I keep wanting to refer to it as a symbolic constant< g >) involving a function is evaluated at run-time. The theory (at least mine) is that the compiler inserts the function reference wherever the symbol appears.

It's really not a particularly big hit in doing so (I think you'd probably have to get up into the millions of references for it to start to be noticed). Still, if your work involves such things (Bruce Campbell's name comes to mind here) every little bit does matter.
