It depends.  If you built the netCDF-C library as a shared library and you use
version 4.4 or later of the netCDF-Fortran library, and your Fortran com[pilers
support the Fortran-2003 C-compatibility feature, then you should be able to
use the same netCDF-C library with multiple Fortran compilers.  However, we
don't test that capability, and only test with GNU Fortran on some platforms,
so you may run into problems we haven't anticipated.

The -fc flag used by nc-config just records the compiler with which the
netCDF-Fortran library was compiled when nc-config was built, and if there are
multiple netCD-Fortran libraries, it records the one found first when nc-config
was built.  I think it would generally be better to use the nf-config utility 
rather
than the nc-config utility for this information, because, the nf-config utility 
is
associated with the library with which it was installed.
