@tschwinge since he did quite a bit of work on getting autoreconf to
work in the GCC-13 cycle.
This does not address the issues with regenerating lib code, but it
does make things somewhat smoother for cases where the updates are
only in Makefile.am, configure.ac or libtool.m4 for example.
It is based on a patch I've been using on the release branches for
Darwin (written because I wasted a day on a warning missed among the
wall of output).
You should now be able to run "autoreconf -fv" in the libgfortran
directory with only informational output (no warnings).
So far only tested very lightly on trunk - but posting early in case
it helps the way forward.
thanks
Iain
