Currently we display the addresses of the semantic values. Instead, print the values. Add support for YY_USE across languages. * data/skeletons/c.m4, data/skeletons/d.m4 (b4_use): New. * data/skeletons/bison.m4 (b4_symbol_actions): Use b4_use to be portable to D. Add support for %printer, and use it. * data/skeletons/d.m4: Instead of duplicating what's already in c-like.m4, include it. (b4_symbol_action): New. Differs from the one in bison.m4 in that it uses yyval/yyloc instead of *yyvaluep and *yylocationp. * data/skeletons/lalr1.d (yy_symbol_print): Avoid calls to formatting, just call write directly. Use the %printer. * examples/d/calc/calc.y: Specify a printer. Enable traces when $YYDEBUG is set. * tests/calc.at: Fix the use of %printer with D.
