Thanks for the hints

I would try them out, but I went and grabbed new versions from 
which seem to work better.  The "explicit" problem is still there, but
the %g4 problem seems to be gone.

However, this raises another question.  Whenever I compile I get many
warnings from gcc about volatile not doing what might be expected and
using call-clobbered global registers (or something like that).  Are
these warnings important, especially the call-clobbered global
register?  I've been using the result on various things, and the
answer has always been what was expected.
