Explicitly extract TREE_TYPEs for source and mold. Use these to calculate length of source and mold, except for characters, where the se string_length is used. For mold, the TREE_TYPE is recalculated using gfc_get_character_type_len so that the result is correctly cast for character literals and substrings. Do not use gfc_typenode_for_spec for the final cast. 2006-03-22 Paul Thomas <pault@gcc.gnu.org> PR fortran/31193 * gfortran.dg/transfer_array_intrinsic_3.f90: New test. From-SVN: r123131
