Um, then, I guess I don't understand.  Surely it's easy enough to avoid
it on any machine, then, just by telling gcc that the FP registers work
like the i386 or m68k FP registers and can't hold arbitrary values?  I
thought someone said that it was difficult to teach gcc to not do this,
which seemed at odds with gcc already knowing how to not do this.
