we are not even promised that ptrdiff_t is large enough to hold a

ISTR we don't *have* a uintptr_t on all architectures, or that would
be the appropriate thing to use in these 32/64 bit ABI scenarios.
Use unsigned long or uintptr_t instead.
I suspect you mean "unsigned long long"...
No he doesn't. "unsigned long" is guaranteed to be large enough to
hold a pointer (at least on Linux anyway).
On a 32-bit arch "unsigned long" is 32-bit and pointers are 32-bit.
On a 64-bit archi "unsigned long" is 64-bit and pointers are 64-bit.
