* doc/tm.texi: Document Rename TARGET_VECTOR_TYPES_COMPATIBLE to
        TARGET_VECTOR_OPAQUE_P.  Document accordingly.

        * testsuite/gcc.dg/20030218-1.c: Check that initialization of
        opaque types fail.

        * c-typeck.c (comptypes): Change call to vector_types_compatible
        to vector_opaque_p.
        (convert_for_assignment): Call vector_opaque_p instead of
        vector_types_compatible.
        (really_start_incremental_init): Disallow initialization of opaque
        types.

        * target-def.h: Remove TARGET_VECTOR_TYPES_COMPATIBLE.
        Define TARGET_VECTOR_OPAQUE_P.
        (TARGET_INITIALIZER): Same.

        * target.h (struct gcc_target): Remove vector_types_compatible.
        Add vector_opaque_p.

        * config/rs6000/rs6000.c (rs6000_spe_vector_types_compatible):
        Remove.
        (is_ev64_opaque_type): Check for TARGET_SPE and make sure type is
        a vector type.  Change return type to bool.
        (TARGET_VECTOR_TYPES_COMPATIBLE): Remove.
        (TARGET_VECTOR_OPAQUE_P): Define.

        * cp/parser.c (cp_parser_init_declarator): Call vector_opaque_p
        target hook.
        Include target.h.
        (cp_parser_init_declarator): Fix typo in function comments.
