-/* XXX QUAD stuff is not currently supported on most systems.
- Specifically, perl internals don't support long long. Among
- the many problems is that some compilers support long long,
- but the underlying library functions (such as sprintf) don't.
- Some things do work (such as quad pack/unpack on convex);
- also some systems use long long for the fpos_t typedef. That
- seems to work too.

The IV type is supposed to be long enough to hold any integral

+/* 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
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.
