This is not the right list: see the posting guide. But .Fortran is
intended for *Fortran 77* code (as the help page says), and maps the
supplied NAME argument in the same way as the Fortran 77 compiler does,
which is often different from the way the C compiler does.
I would strongly recommend that new code uses .Call and a C wrapper to
F90 code: it is a safer and more portable route.
If you want any more help, you need to follow the posting guide and
- post to R-devel,
- supply the 'at a minimum information' asked for there,
- supply the minimal example asked for, and what the messages you see are.
