IA64 does.  Not only does Alpha not define it, but I'm told it never
will.  Bleah.  So we do have to find a different solution.

Maybe we should just use __LP64__ everywhere?
I'm not sure.  This was added to let the interpreter work on IA64.

This leads to problems of various sorts.

One big problem is deciding where to install this config.h.  We'd want
to make it always visible.  But it also has to go into a
architecture-dependent directory (if we want to conform to the GNU
coding standards).

We'd also have to rename all the macros in config.h.
(libjpeg doesn't do this and the result is hell.)
