Beware of LP32 systems (ILP32, ILP32LL64). Such systems have been

Summary: a long long system needs to add -DUSE_LONG_LONG to $ccflags
to get quads -- and if its pointers are still 32 bits, this will break
binary compatibility. Casting an IV (a long long) to a pointer will
- truncate half of the IV away.
