In C, ignoring POSIX, a void pointer is big enough to hold any pointer
to data. Pointers to data may be different sizes. And a void pointer
can't hold a function pointer, but all function pointers are defined to
be the same size. Thus `void (*)(void)' can be used as a generic
function pointer type and cast to other ones when needed.

That's awful. Might as well say `return' occurs so often, it should
have been `@'. :-)
