!
! This checks for Fortran 2003 extensions.
!
! Argument checks:
! - elements of deferred-shape arrays (= non-dummies) are allowed
! as the memory is contiguous
! - while assumed-shape arrays (= dummy arguments) and pointers are
! not (strides can make them non-contiguous)
! and
! - if the memory is non-contigous, character arguments have as
! storage size only the size of the element itself, check for
! too short actual arguments.
