Useless pointer-to-int-cast warning?

[Vincent Lefevre]

What's the point of the pointer-to-int-cast warning, which is
enabled by -Wall?

I get this warning under 32-bit Linux when casting a pointer to
uintmax_t. I use uintmax_t to make sure that the integer size is
large enough. So, what's the problem?
