Much harder ?

I don't think anybody who tries to build GCC from source will have any
problem building MPFR first.

I can see how a distribution will probably want to have at least the
MPFR version GCC demands, which would force an MPFR upgrade to
accompany a GCC 4.4 package.

That's why I said "before branching", this gives a time window to detect
such regressions. While the cutoff date for moving to a new revision
of MPFR may be somewhat earlier, my idea was to demand a rather current
revision.

Changing to 3.0.0 - which implies much larger changes than 2.3.3 - is
IMHO stage 1 material, maybe stage 2 if the release notes make it
exceedingly clear that the major version change is only because
of major new features, with no changes to existing ones.
