Hello Thomas,

I tried it and it worked fine.

Just a few remarks:
- gfortran complained about bind(c,'NAME'), but it accepted
  bind(c,name='NAME').
  (I am not sure if the first form is legal syntax)
- gfortran also warned about the fact that the arguments
  to the routine did not have the bind(c) attribute. Not a
  big problem in this experiment, but if this gets used
  by unsuspected users, then I will need to suppress them
  (by supplying the bind(c) attribute of course).

Regards,

Arjen
