! Check whether MODULE PROCEDUREs are properly treated
! They need to be contained in a procedure, i.e. an
! interface in another procedure is invalid; they may, however,
! come from a use-associated procedure.
! (The PROCEDURE statement allows also for non-module procedures
! if there is an explicit interface.)
