We should instead revert

2009-08-18  Michael Matz  <matz@suse.de>

        * trans-expr.c (gfc_conv_substring): Don't evaluate casted decl early,
        change order of length calculation to (end - start) + 1.
        (gfc_get_interface_mapping_array): Adjust call to
        gfc_get_nodesc_array_type.
...
        * trans-decl.c (gfc_finish_var_decl): Give scalars that can't be
        aliased a type with a different alias set than the base type.
        (gfc_build_dummy_array_decl): Adjust call to gfc_get_nodesc_array_type.

for now.

Richard.
