We still have a few old C casts in lalr1.cc, let's get rid of them. Reported by Frank Heckenbach. Actually, let's monitor all our casts using easy to grep macros. Let's use these macros to use the C++ standard casts when we are in C++. * data/skeletons/c.m4 (b4_cast_define): New. * data/skeletons/glr.c, data/skeletons/glr.cc, * data/skeletons/lalr1.cc, data/skeletons/stack.hh, * data/skeletons/yacc.c: Use it and/or its casts. * tests/actions.at, tests/cxx-type.at, * tests/glr-regression.at, tests/headers.at, tests/torture.at, * tests/types.at: Use YY_CAST instead of C casts. * configure.ac (warn_cxx): Add -Wold-style-cast. * doc/bison.texi: Disable it.
