Mike,

I don't think you can do what you hope to do.  The syntax you're
suggesting seems to imply preprocessor directives, but these are
completed before the code ever gets to the compiler, so I would think
that in order to turn off warnings for a section of your code there
would have to be defined ansi c syntax for disabling it in that
portion.  I'd think that there is not that syntax.  My guess is you'll
have to either live with the warnings, fix what it's warning you
about, turn off -Wall so it doesn't warn you anywhere, or turn on a
smaller subset of warnings (see all the -W flags in the manpage) that
maybe refines what you want.  My guess is you might have to live with
it.  Of course, maybe I'm just wrong or don't understand your
question.

Hope this helps.  Take care,

Daniel
