Hi Vincent, thanks for making this release.  Since this version of mpfr
fixes important bugs encountered by GCC, I've updated the gcc
documentation and error messages to refer to version 2.2.1.

I have NOT (yet) updated gcc's configure to force the issue.  I'll wait a
little while to let people upgrade.


Gerald, would you please copy the mpfr-2-2.1 tarball to the gcc
infrastructure directory and delete 2.2.0 and the cumulative patch from
there?  Thanks. http://www.mpfr.org/mpfr-current/mpfr-2.2.1.tar.bz2
