If you don't need fortran, then by all means just skip it.
Set your environment variable FC to null, and try again. (Do a "make
distclean" first).
In sh, I can do it like this:
make distclean && FC= ./configure && make check
If you want the fortran interface, I would suggest getting the latest
version of gcc.
There have been a lot of changes in gfortran in the last few versions
of gcc, so hopefully upgrading to the latest version of gfortran will
fix your problem, which I have never seen before!
Thanks,
Ed
