        * doc/objc.texi (Type encoding): Added the new 'long double' (D)
        code.  Added byref, which was missing in the list of codes.
        Explain that enumeration values are encoded as the integer type
        that the compiler uses to store them.  Explain and make examples
        of how 'const' interacts with pointers, and the complication of
        the encoding of 'const char *'.
        (Legacy type encoding): New subsection, explaining that GCC emits
        incorrect type encodings for the NeXT runtime for compatibility
        reasons.
        (@@encode): New subsection, explaining @encode and particularly
        that protocol qualifiers are not recognized inside an @encode()
        expression.
        (Method signatures): New subsection, explaining how method
        signatures are encoded.

        * objc-act.c: Improved comments for encoding functions.
        (encode_aggregate_within): For the GNU runtime, rewritten some
        obsfuscated code to clarify the various cases.
        (encode_aggregate): Function removed.
        (encode_array): Generate an error if asked to encode an incomplete
        array as part of generating instance variables.  Else, when
        encoding an incomplete array inside a structure, encode it as an
        array of zero size.
        (encode_pointer): For the GNU runtime, fixed encoding 'BOOL *' as
        '^c' instead of '*'.
        (encode_gnu_bitfield): Encode enumerated types exactly in the same
        type as integer types instead of using a hardcoded 'i'.  If asked
        to encode a non-integer type as a bitfield, do not abort
        compilation immediately; instead generate an error, then skip the
        type.
        (encode_type): Use a 'switch' instead of a sequence of 'if's.
        Added a 'default' clause that gets executed if the type can not be
        matched, and that encodes it as '?' (unknown) and produces a
        warning.  For the GNU runtime, encode enumerated types exactly in
        the same way as integer types instead of using a hardcoded 'i'.
        Encode long double as 'D'.  Encode 128-bit integers as 'T' or 't'.
        Encode C++ reference types as pointers.  Call encode_vector to
        encode vectors.
        (encode_vector): New function.
