| That, and why is it cast to an unsigned long and not uintptr_t?
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.
