Ah-ha! You're right. Now I see that this warning is issued by
preprocessor, not by compiler. Now that I think about it, it seems
logical. Preprocessor has to tokenize input to perform substitutions
and such, so even if code isn't meant for compiler, it must follow
some rules - ifdefined parts of code are not comments. Is that right?

I really hate this damn machine, I wish that they would sell it.
It never does just what I want, but only what I tell it.
