+
+ yysyntax_error: avoid duplicate lookahead collection.
+ Except when memory reallocation is required, this change
+ eliminates the need to invoke yysyntax_error twice and thus to
+ repeat the collection of lookaheads. It also prepares for
+ future extensions that will make those repetitions more
+ expensive and that will require additional memory management in
+ yysyntax_error. Finally, it fixes an obscure bug already
+ exercised in the test suite.
+ * data/yacc.c (yysyntax_error): Add arguments for message
+ buffer variables stored in the parser. Instead of size, return
+ status similar to yyparse status but indicating success of
+ message creation. Other than the actual reallocation of the
+ message buffer, import and clean up memory management code
+ from...
+ (yyparse, yypush_parse): ... here.
+ * tests/regression.at (%error-verbose overflow): No longer an
+ expected failure.

+ * data/glr.c, data/lalr1.cc, data/lalr1.java, data/yacc.c: Fix

+ * data/glr.c (yyis_pact_ninf): Rename to...

+ (yyisDefaultedState): Update for rename.
+ (yyis_table_ninf): Rename to...
+ (yytable_value_is_error): ... this, and check for value zero
+ besides just YYTABLE_NINF.
+ (yygetLRActions): Check for default value from yypact. It
+ appears that this check is always performed before this function
+ is invoked, and so adding the check here is probably redundant.
+ However, the code may evolve after this subtlety is forgotten.
+ Also, update for rename to yytable_value_is_error. Because that
+ macro now checks for zero, a different but equivalent branch of
+ the if-then-else here is evaluated.
