I might be clang none the less because gcc point to clang on a Mac.  I'd
know if you'd posted the version!  Help us to help you.

As far as I know, once you've used -w on the command line (as you once
suggested), you can't turn any warnings back on.

You can use -Wno-all and then use a pragma to turn -Wall on for the code
you want.  You could also use -Wno-everything and turn on the warnings
you want later on.  But it might be better to use the pragmas to turn
the warnings off.

However, this reply may be waste of time.  You reported a program with
pragmas that I can't reproduce.  Post code and versions, so we can help.
