Correction: that's not exactly how uintptr_t is defined.

"The following type designates an unsigned integer type with the
property that any valid pointer to void can be converted to this type,
then converted back to a pointer to void, and the result will compare
equal to the original pointer: uintptr_t"

"On XSI-conformant systems, the intptr_t and uintptr_t types are
required; otherwise, they are optional."
