What I did on the Amiga was to add the #ifdefs in my sources as well as in the include files, which permits you to be lazy but enables you to "optimize" whenever I cared for it. Normally I prefer to go for code clarity, because all the #ifdefs in the source is just distracting. Basically, don't worry about it.
