I only mention it by analogy with AltiVec, which needs a larger
jumpbuf.  Which reminds me - does Red Hat have plans to submit any
patches which would cover AltiVec setjmp/longjmp, and if not and I
repost the patch I sent several times this summer, would it at least
get a little more reaction?

Some of the configury would probably have to change, given the decision
to use new triplets.
