#496 Casting void * to pointer to function

[Vladimir Támara Patińo]

void *p;
extern void g(int (*h)(int));

void f() {
g((int (*)(int))p);
}

Anyone have any idea if the original cast is legal C?

On the other hand, the next fragment works perfectly fine
and produces the same code as I would expect from the
former if it did not generate an error.

void *p;
extern void g(int (*h)(int));

void f() {
int (*fp)(int) = p;
g(fp);
}

Greets,
