HEADER FILE:
For "ISO_Fortran_binding.h", we use:
   #include "../../../libgfortran/ISO_Fortran_binding.h"
Can you check whether something like that also works for 'omp.h'?
(Additional "../" and "libgomp/".)

Can you check whether that helps? For some reasons, those do
not fail here.

FORTRAN MODULE
Then I have the question why, e.g., "use openacc_kinds" in
gfortran.dg/goacc/acc_on_device-2.f95 does work. What's different there?

The *exp file does not seem to be any different (except that goacc.exp
adds "dg-compile-aux-modules").
