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