        * m4/ifunction.m4 (name`'rtype_qual`_'atype_code): ditto.
        If retarray->data is NULL (i.e. the front end does not
        know the rank and dimenson of the array), fill in its
        properties and allocate memory.
        Change the assertions about rank and dimension of retarray into
        runtime errors and only check them for retarray->data != NULL.
        Do the same for correcting the stride from 0 to 1 in retarray.
        (`m'name`'rtype_qual`_'atype_code): Likewise.
        * m4/iforeach.m4 (name`'rtype_qual`_'atype_code): Likewise.
        Change assertion about rank of array to runtime error.
