It is different from #ifdef (or #ifndef if you wish ;-) in that #ifdef is
not a comment - comments are comments, #ifdef is a compiler directive of
which only purpose is to state something to the compiler. Leaving comments
out should not alter the behaviour of what is
executed/interpreted/compiled, while leaving out #ifdef's most certainly
can and even should.
