Thu May  7 10:29:24 1998  Tim Janik  <timj@gtk.org>

        * gtk/gtksignal.c (gtk_signal_newv): suport middle dashes ('-') in
        signal names, e.g. "signal-name" is now an alias for "signal_name".
        (gtk_signal_handler_new): allocate handlers through a global handler
        structure list, that's faster than memchunks.
        (gtk_emission_new): allocate emissions through a global emission
        structure list, that's faster than memchunks.
