+       * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
+       true since it's then always used regardless of whether yyoverflow is
+       defined.  Reported by Christian Burger at
+       <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
+       * THANKS: Add Christian Burger.

+       * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
+       determine whether this function has already complained about an invalid
+       value for a %define boolean variable, don't check whether Bison has
+       ever examined the value.  As written, the check was a tautology.
+       Instead, record and check for this complaint using a separate muscle.

+       Fix push parsing memory leak reported by Brandon Lucia at
+       <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
+       * THANKS: Add Brandon Lucia.
+       * data/push.c (yypstate_delete): Free the stack if it was reallocated
+       but the parse never completed and thus freed it.
+       * tests/Makefile.am (TESTSUITE_AT): Add push.at.
+       * tests/testsuite.at: Include push.at.
+       * test/push.at: New.
+       (Push Parsing: Memory Leak for Early Deletion): New test case.
