   1 ! { dg-do compile }
   2 ! this is to simply test that the various ways the use statement can
   3 ! appear are handled by the compiler, since i did a special treatment
   4 ! of the intrinsic iso_c_binding module.  note: if the user doesn't
   5 ! provide the 'intrinsic' keyword, the compiler will check for a user
   6 ! provided module by the name of iso_c_binding before using the
   7 ! intrinsic one.  --Rickett, 09.26.06
