PR 36299 asks to not warn for (&a =3D=3D 0). Ideally, we should allow users=
 to
workaround the warning by using a pointer cast on the variable but warn for=
=20
(void *)0. I think this would be a reasonable middle-ground.

But at the end, someone has to dig in the code and implement whatever he ca=
n.
This part of the C FE is not very pretty.
