My concern here was whether or not it's likely to ever be a binary
compatibility snag.  After actually waking up today, I guess it
wouldn't be moreso than, say, compiling with -m7400 anyway.

It seems reasonable to me to do the #define for setjmp() and to
not worry about restoring for signals.  Pthreads, however, should
probably be saving/restoring.
