Oh, yes there is.
if (CONFIG_FOO) { .... } else { .... }

WTF _is_ Source Navigator? I'm not kidding - I have no idea what the thing is. My IDE is nvi and I don't touch userland code I don't use. World is full of crappy code, so I don't particulary care for random GUI stuff, no matter where it comes from.
