That's very prolix syntax.  It would be quite unfortunate if you have to
write three #pragmas just to disable one warning.

I'd much prefer something more similar to the current `__extension__'.
For example `__nowarn__', used as a prefix on an expression,
declaration, or statement, could disable all warnings for just that
expression/declaration/statement.  Alternatively,
`__disablewarn__(NAME)' could be used in the same contexts to
selectively disable specific warnings.
