+ * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check
+ that '#include <cstdlib>' works.
+ * src/system.h (INT8_MIN, INT16_MIN, INT32_MIN, INT8_MAX):
+ (INT16_MAX, UINT8_MAX, INT32_MAX, UINT16_MAX, UINT32_MAX):
+ #undef if ! defined __STDC_VERSION__ || __STDC_VERSION__ < 199901,

+
+ * bootstrap: Undo changes to gnulib files that autoreconf made.
+
+ Minor fixups to get 'make maintainer-check' to work.
+ * configure.ac: Don't use -Wnested-externs, as it's incompatible

+ * lib/subpipe.c (end_of_output_subpipe): The args are unused.

+ In yyerror, use the msg arg.
+ (Corrupted semantic options if user action cuts parse):
+ (Incorrect lookahead during deterministic GLR):
+ (Incorrect lookahead during nondeterministic GLR):
+ Don't name a local var 'index'; it shadows string.h's 'index'.
