Yes, I looked into cfortran. Took me a while to find my way through the
docs, but it seems there is no mention of modules at all. The Fortran
code I want to call is not under my control, and I don't want to patch
it. Else I would add BIND(C) calls where necessary. For the same reason,
I can't move the subroutine out of its module either.

With cfortran, I end up with this linker error:

... undefined reference to `NESTRUN_'

Since cfortran doesn't deal with modules, that is the wrong name, should
be __nested_MOD_nestrun. Apart from that, cfortran.h did what it
promised to.
@Bastien: If I understand correctly, this is not a bug of cfortran, it
just doesn't support modules, right? Is module support part of what you
want to add when modernizing cfortran.h?
