+       * data/yacc.c (YYSIZE_MAXIMUM): New macro.
+       (YYSTACK_ALLOC_MAXIMUM): Use it.
+       (yysyntax_error): New function.
+       (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
+       multiple syntax errors are reported, and alloca is being used.
+       Instead, reallocate buffers twice as big each time, so that
+       we waste at most half the allocated memory.  Start with a small
+       (128-byte) buffer that will suffice in most cases anyway.
+       Use yysyntax_error to do most of the work.
+
+       * doc/bison.texinfo (Error Reporting, Table of Symbols):
+       yynerrs is the number of errors reported, not the number of
+       errors encountered.
+
        * tests/glr-regression.at (Duplicated user destructor for lookahead):
        Mark it as expected to fail.
        Cast result of malloc; problem reported by twlevo@xs4all.nl.
