It would still be very helpful if you could type "gfortran --v" and
"gcc -v" and report what the result is.

Warnings are not important.

I suspect that your compiler does not support the ISO_C interface, but that
somehow the configuration script thought that it did. This is why we
need version numbers. It is also required that gcc and gfortran use the same
version of the compilers.

A workaround (depending on your needs) is to re-configure using the -nofftw3
