Okay I checked gmp source tarballs, and it looks like the SUNPRO clauses
defining __GMP_EXTERN_INLINE were added specifically in gmp-4.3.1.  I don't see
them in gmp-4.2.4 or gmp-4.3.0.  Could you please verify bootstrapping gcc with
those two versions of gmp plus Sun's cc to see if they work?  If it does we
should offer it as a workaround for users until we figure out how we want to
solve this long-term.

Recommending other versions of gmp as a workaround is helpful even if we hack
up a patch to GCC, because gcc-4.3 and 4.4 will not see these "fixes" until
some months in the future when we do another release.  Alternatively we may end
up recommending to the gmp maintainer(s) that they fix the problem in their
package since that's what's really broken IMHO.  Either way, it would be
helpful to know whether using other versions of gmp would help.

Thanks.
