Well...if the SPAC is a sparc64.  But otherwise, you've got two 32-bit
machines there, with nothing to smoke out word-size dependencies.

Of course, if you really want to do a good job of portability testing,
throw in some even less "standard" machines, like, say, a PDP-10 (or
more likely a simulator) and a Lisp Machine.  (I've been told C
compilers exist for Lisp Machines, and they are great at finding
assumptions like "all the world's a byte-addressed flat address space",
since their pointers really do take advantage of the freedom the spec
offers about how pointers work.)
