! Tests for C760:
! The passed-object dummy argument shall be a scalar, nonpointer, nonallocatable
! dummy data object with the same declared type as the type being defined;
! all of its length type parameters shall be assumed; it shall be polymorphic
! (7.3.2.3) if and only if the type being defined is extensible (7.5.7).
! It shall not have the VALUE attribute.
!
! C757 If the procedure pointer component has an implicit interface or has no
! arguments, NOPASS shall be specified.
!
! C758 If PASS (arg-name) appears, the interface of the procedure pointer
! component shall have a dummy argument named arg-name.
