+
+	* src/main.c (main): If there are complains after grammar
+	reductions, then output the report anyway if requested, then die.
+	* src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
+	* src/reader.c (eoftoken): New.
+	(parse_token_decl): If the token being defined has value `0', it
+	is the eoftoken.
+	(packsymbols): No longer hack `tags' to insert `$' by hand.
+	Be sure to preserve the value of the eoftoken.
+	(reader): Make sure eoftoken is defined.
+	Initialize nsyms to 0: now eoftoken is created just like the others.
+	* src/print.c (print_grammar): Don't special case the eof token.
+	* src/regression.at: Adjust: `$' has value 0, not -1, which was a
+	lie anyway, albeit pleasant.
+	* tests/calc.at: Exercise error messages with eoftoken.
+	Change the grammar so that empty input is invalid.
+	Adjust expectations.
+	When yyungeting, be sure to use a valid yylloc: use last_yylloc.
+

+
+	* configure.in: Check the protos of strchr ans strspn.
+	Replace strchr if needed.
+	* src/system.h: Provide the protos of strchr, strspn and memchr if
+	missing.
+	* lib/strchr.c: New.
+	* src/reader.c (symbols_save): Use strchr.

+
+	* src/print.c, src/print_graph.c (escape): New.
+	Use it to quote the TAGS outputs.
+	* src/print_graph.c (print_state): Now errors are in red, and
+	reductions in green.
+	Prefer high to wide: output the state number on a line of its own.
+

+
+	* src/state.h, src/state.c (reductions_new): New.

+	* src/print.c (print_reductions, print_actions): Adjust.
