* To support platform where unsigned long cannot be used interchangeably with
* inptr_t (e.g. CHERI-extended ISAs), we can use the stdint.h intptr_t.
* Ideally, we could just use (u)intptr_t everywhere, but this could result in
* ABI breakage if khronos_uintptr_t is changed from unsigned long to
* unsigned long long or similar (this results in different C++ name mangling).
* To avoid changes for existing platforms, we restrict usage of intptr_t to
* platforms where the size of a pointer is larger than the size of long.
