Don't confuse the language with the implementation you happen to use.  On
most unix systems the # directives are handled by a separate pass before the
rest of the compiler, but there are lots of versions where it's all done in
one pass.  The ANSI C standard says quite a lot about what preprocessor
actions are supposed to do without saying anything about how they're
supposed to be implemented.
