Is there any chance you could post your local patches that require
MPFR 2.2 to the fortran and/or gcc-patches list? I'm curious to
see how you propose to use the new subnormal functionality, atan2
implementation, etc... I think these are all good reasons to upgrade
MPFR (and pre-requisites should the middle-end decide to use
MPFR itself), but it might be possible to utilize autoconf's HAVE_
macros to reach a compromise whereby we make use of the fixed
and extended functionality where available, without completely
sacrificing the existing gfortran 4.1/4.2 functionality on systems
that haven't yet upgraded.
Perhaps such a compromise is impossible, as your intended changes
are significantly invasive, but without learning more about your
plans its difficult for folks to appreciate the costs vs. benefits.
