bfd_hostptr_t is defined as a type large enough to hold either a long or a pointer. It mostly appears in the coff backend code in casts. include/coff/internal.h struct internal_syment and union internal_auxent have the only uses in data structures, where comparison with include/coff/external.h and other code reveals that the type only needs to be large enough for a 32-bit integer or a pointer. That should mean replacing with uintptr_t is OK.
