+ Output `undef_token_number'.
+ * data/bison.simple, data/bison.c++: Use them.

+ * tests/torture.at (Big triangle): Move the limit from 254 to
+ 500.
+ * tests/regression.at (Web2c Actions): Ajust.
+
+ Trying with bigger grammars shows various phenomena: at 3000 (28Mb
+ of grammar file) bison is killed by my system, at 2000 (12Mb) bison
+ passes, but produces negative #line number, once fixed, GCC is
+ killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
+ C), it passes.
+ * src/state.h (state_h): Code input lines on ints, not shorts.
