Hm, gnatgcc gives the same error:

  gnatgcc -Wall -o test_c test_c.c -I/usr/local/include/opensteuer -lopensteuer -lgnat
  ld: cannot find -lgnat

Is there anything else I need to configure?

I want to keep it portable with other Linux-distros (if possible) as
the code is public.  Would it be better to use gnatgcc oder gcc then?

thx, Martin
