You basically answered your own question -- the * is added in
order to get a pointer to the right type and of the right width,
and that is what breaks in your case, because not all types can
correctly have * appended to produce pointers to those types.

The obvious solution is to use a typedef for (void (*)()) and
use that in the invocation of va_arg().
