        * intrinsic.c (gfc_convert_chartype): Don't mark conversion
        function as pure.
        * trans-array.c (gfc_trans_array_ctor_element): Divide element
        size by the size of one character to obtain length.
        * iresolve.c (gfc_resolve_cshift): Call the _char4 variant when
        appropriate.
        (gfc_resolve_eoshift): Likewise.
        * trans-intrinsic.c (gfc_conv_intrinsic_ctime): Minor beautification.
        (gfc_conv_intrinsic_fdate): Minor beautification.
        (gfc_conv_intrinsic_ttynam): Minor beautification.
        (gfc_conv_intrinsic_minmax_char): Allow all character kinds.
        (size_of_string_in_bytes): New function.
        (gfc_conv_intrinsic_size): Call size_of_string_in_bytes for
        character expressions.
        (gfc_conv_intrinsic_sizeof): Likewise.
        (gfc_conv_intrinsic_array_transfer): Likewise.
        (gfc_conv_intrinsic_trim): Allow all character kinds. Minor
        beautification.
        (gfc_conv_intrinsic_repeat): Fix comment typo.
        * simplify.c (gfc_convert_char_constant): Take care of conversion
        of array constructors.

        * intrinsics/string_intrinsics_inc.c (string_index): Return
        correct value for zero-length substring.
        * intrinsics/cshift0.c: Add _char4 variant.
        * intrinsics/eoshift0.c (eoshift0): Allow filler to be a pattern
        wider than a single byte. Add _char4 variant and use above
        functionality.
        * intrinsics/eoshift2.c (eoshift2): Likewise.
        * m4/eoshift1.m4: Likewise.
        * m4/eoshift3.m4: Likewise.
        * m4/cshift1.m4: Add _char4 variants.
        * gfortran.map (GFORTRAN_1.1): Add _gfortran_cshift0_1_char4,
        _gfortran_cshift0_2_char4, _gfortran_cshift0_4_char4,
        _gfortran_cshift0_8_char4, _gfortran_cshift1_16_char4,
