 ! The following interface does in principle

 ! not match the procedure (missing VALUE attribute)

 ! However, this occures in real-world code calling

 ! C routines where an interface is better than

 ! "external" only.

! The following test is possible and

! accepted by other compilers, but

! does not make much sense.

! Either one uses VALUE then %VAL is

! not needed or the function will give

! wrong results.
