Be careful there. Conditional compilation can be dangerous. For instance,
how to you guarantee that you've tested all the various permutations of
the conditions? Then there's the fact that it can make the code incredibly
difficult to read (look at all the confusion lately with the _SFR_*
macros). Kernighan and Pike's "The Practice of Programming" has a good
discussion on this (among many excellent discussions).
