        * gfortran.h (gfc_check_same_strlen): Made public.
        * trans.h (gfc_trans_same_strlen_check): Made public.
        * check.c (gfc_check_same_strlen): Made public and adapted error
        message output to be useful not only for intrinsics.
        (gfc_check_merge): Adapt to gfc_check_same_strlen change.
        * expr.c (gfc_check_pointer_assign): Use gfc_check_same_strlen for
        string length compile-time check.
        * trans-expr.c (gfc_trans_pointer_assignment): Add runtime-check for
        equal string lengths using gfc_trans_same_strlen_check.
        * trans-intrinsic.c (gfc_trans_same_strlen_check): Renamed and made
        public from conv_same_strlen_check.
        (gfc_conv_intrinsic_merge): Adapted accordingly.
