Function pointer casts are broken

[Thierry Delisle]

I need this to work for external scheduling :

extern void save( void (*func)() );

void foo( int a ) {
	save( &foo );
}

What do we actually want there? This does not work in C++, and since we're aiming for stronger types like C++, I don't think we can make this work without an explicit cast.

This would be fine for me but it also doesn't work :

typedef void (*generic_func_t)();

extern void save( generic_func_t func );

void foo( int a ) {
	save( (generic_func_t)foo );
}

Okay, I think I've fixed this. Just running the tests now.
