I think it's worth doing. Move the warned variable up and then the
check will be less expensive, maybe.

On the mac I have access to via Nelson, configure needs to be told
to look for MPFR at the top level.  I don't understand why for Hermann
the top level finds it but the extension one doesn't; they use the
same snippets.  That is worth investigating separately but Hermann
will have to try to figure it out.

Thanks,
