bison/tests/actions.at port to GCC 3.4.0

[Paul Eggert]

I installed this obvious minor patch to port to GCC 3.4.0:

2004-04-27  Paul Eggert  <address@hidden>

        * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
        declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
        unused declaration.
