All of those. There shouldn't be anywhere you could put __nowarn__
that you couldn't put a _Pragma, since that is a preprocessing
directive, not part of the C grammar. Nor can I see why one would
work for some warning that the other did not work for. The natural
usage style is somewhat different, depending on how the pragma is
defined... and obviously the implementation would be very different.
