commit r12-4360-g4ca446a46bef8c127d7aaeb2d4bb4625edc7f84e
Author: Eric Gallager <egallager@gcc.gnu.org>

    Mark certain subdirectories as missing TAGS targets.
    
    The subdirectories in question are libcody,
    libdecnumber, c++tools, libgcc, and libobjc.
    This is progress towards allowing "make tags" to
    work from the top-level directory; a few additional
    changes may also be necessary, though.
    
    ChangeLog:
    
            * Makefile.def: Mark libcody, libdecnumber,
            c++tools, libgcc, and libobjc as missing TAGS
            targets.
            * Makefile.in: Regenerate.
