Hi Jeff, thanks for the bug report. * Daily, Jeff A wrote on Thu, Jan 20, 2011 at 07:46:06PM CET: > Our software is a mostly C, with some Fortran and a C++ binding.

Can you submit a patch (to the -patches list)? You're in the best position to test it. Can you also try to ensure that one of the Autoconf testsuite Fortran tests exposes this if $F77, $FFLAGS and/or $FC, $FCFLAGS are suitably set in the environment so this library is pulled in? In git master, the Fortran tests are make check TESTSUITEFLAGS='303-329' (we should probably use AT_KEYWORDS a bit more). If you need help, feel free to report back with what you have.
