-/* We should be able to get Quad_t in most systems:
- all of int64_t, long long, long, int, will work.
-
- Beware of LP32 systems (ILP32, ILP32LL64). Such systems have been
- used to sizeof(long) == sizeof(foo*). This is a bad assumption
- because then IV/UV have been 32 bits, too. Which, in turn means
- that even if the system has quads (e.g. long long), IV cannot be a
- quad. Introducing a 64-bit IV (because of long long existing)
- will introduce binary incompatibility.
-
- 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. Most systems can just use
- Configure -Duse64bits to get the -DUSE_LONG_LONG added either by
- their hints files, or directly by Configure if they are using gcc.
