Don't you think that forcing people to cast pointers is much much more
dangerous than allowing simple equivalence of pointers when they aren't even
being derefenced?
What about this:
struct x *f() { return ptr;}

yes it is, since it is invalid code, I repeat it is invalid code. How many
more times do I need to repeat that?
Just add a cast to ge

But surely that example isn't evidence of a problem.
Because if somebody codes:
int *p = f();
does it really matter what the signedness of f()'s return value is?
The caller has a pointer which is most definitely

Because the code is really invalid C.
that is:
int *a;
unsigned int *f(void)
{
return a;
}
Is invalid C. We used to just output a warning with -pedantic but now the
warning is always on unless you add -Wno-pointe
