Thanks for the report.  Have you verified whether this bug is still
present in autoconf 2.69?  If it has already been fixed in newer
versions, then all we can do is suggest that packages using older
autoconf upgrade.  If it is still present in autoconf.git, then it would
be worth fixing for 2.70; but I'm no Fortran expert, so I'd appreciate
it if you could write the actual patch.
