So that it does not bring in another header to define uintptr_t.
unsigned long might not be long enough. I'd rather bring in another header than have code that might do the wrong thing on some future platform.
We should probably have a header that defines "__" versions of some useful types without polluting the namespace, and then use __intptr_t.
