As I wrote, one downside is that currently the checking is quite strict
wrt callbacks. The other option is to just check that sizeof(arg) ==
sizeof(void(*)(void)), which is too loose...

Another one which I forgot to mention before is that if the option
argument is an expression that itself generates a warning, the warning
will be output multiple times, each time the __typeof__ keyword is
applied to the expression.

But it shouldn't break stuff, just add some not-so-helpful warnings or
multiply existing ones.
