I haven't heard it mentioned on the lists and it's not in the open
projects file.

After thinking about it I agree that this should be implemented, I
wonder if it would be easy.  there should be a ((no_warn)) attribute
for functions.  Errors would still be errors.  There have to be a
command line switch to forcibly override this too.

This would also be good but would take a lot more work to implement.

If you're stuck you could pipe the output of gcc to 'egrep -v'.  A bit
of a kludge but if it was in a Makefile or script you wouldn't
notice it.

If you're trying to block "unused variable `p'" warnings you could
give the variable the ((unused)) attribute.  That's the only GCC
solution I can think of.
