That was quite a strong wording... Some people might disagree :)

Anyways, as far as I know the preprocessor does not care about where
the preprocessor directives are placed. It just goes through the file
sequentially and macro definitions take effect at the place you write
them. And actual compiler does not see the directive - just code which
has been replaced. So from C point of view I see no problem here. From
coding conventions or guidelines point of view - well, that's more of
your territory ;)
