joerg,
There is another way of doing it as well:

mixing fortran codes compiled with different fortran compilers is
a bad idea in my opinion; especially, if they use the same name
mangling scheme (at least for fortran 77 style calls). you may be
in for very some surprises.

the warning is because intel fortran does not support the -pthread flag.
