It depends to some extent on how that code is set up.
We do conditional function definition in many .h files a la Linux style:
#if CONFIG_THIS == 0
#define x()
#endif
So it's likely that
if (CONFIG_THIS) {
x();
}
would work.
Anyway, I'm not going to worry about this if nobody else does :-)
Just FYI, the romcc code depends on romcc's intelligent optimization.
