c preprocessor expansion

["Task Struct From Hell" <taskstructfromhell@xxxxxxxxxxxxxx>]

Hi,

I was wondering if gcc has any argument which allows for the expansion
of all macros in a file, just so if we have something like the
following:


#define FOO "bar"

int main() {
   printf(FOO);
}

It will output this:

int main() {
   printf("bar");
}

Thanks,
TSFH
