Specifies that type and shape matching rules related to explicit
  interfaces are to be ignored.  This permits the construction of an
  INTERFACE block for an external procedure or a module procedure
  that accepts an argument of any type or shape; for example, a
  memory copying routine.

  NO_ARG_CHECK can appear only in an INTERFACE block for a
  non-generic procedure or in a module procedure.  It can be applied
  to an individual dummy argument name or to the routine name, in
  which case the property is applied to all dummy arguments in that
  interface.

  NO_ARG_CHECK cannot be used for procedures with the PURE or
  ELEMENTAL prefix.  If an argument has an INTENT or OPTIONAL
  attribute, any NO_ARG_CHECK specification is ignored.
