+
+       * doc/bison.texinfo (Prologue, Rules, Actions, Union Decl, Action Decl):
+       (Destructor Decl, Parser Function, Pure Calling):
+       Describe rules for braces inside C code more carefully.
+
+       Be a bit more systematic about using 'abort'.
+       * lib/abitset.c (abitset_test): Remove ATTRIBUTE_UNUSED; not needed.
+       * lib/bitset.c (bitset_bytes, bitset_init, bitset_op4_cmp):
+       Put 'default: abort ();' before some other case, to satisfy older
+       pedantic compilers.
+       * lib/bitset_stats.c (bitset_stats_init): Likewise.
+       * lib/ebitset.c (ebitset_elt_find, ebitset_op3_cmp): Likewise.
+       * lib/lbitset.c (lbitset_elt_find, lbitset_op3_cmp): Likewise.
+       * src/conflicts.c (resolve_sr_conflict): Likewise.
+       * src/LR0.c (save_reductions): Use "if (!FOO) abort ();" rather than
+       "assert (FOO);".
+       * src/state.c (state_transitions_set, state_reductions_set): Likewise.
+       * src/scan-skel.l (QPUTS): Remove unnecessary parens.
+       (BASE_QPUTS, "@output ".*\n): Remove unnecessary asserts.
+

+
+       Fix some porting glitches found by Nelson H. F. Beebe.
+       * lib/abitset.c (abitset_resize): Rewrite to avoid warnings from
+       compilers that don't understand that abort () does not return.
+       * src/state.c (transitions_to): Likewise.
+       * 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,
+       for the benefit of some pre-C99 compilers.
+
+       * 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
+       with the new verify.h implementation.
+       * data/c.m4 (b4_yy_symbol_print_generate): YYUSE (yyoutput).
+       * data/glr.c (YYUSE): Depend on __GNUC__ as well.
+       * data/yacc.c (YYUSE): Likewise.
+       * data/lalr1.cc (yysyntax_error_): YYUSE (yystate).
+       * lib/subpipe.c (end_of_output_subpipe): The args are unused.
+       * src/parse-gram.y (declaration): Don't pass a string constant
+       to a function that expects char *, since GCC might complain
+       about the constant value.
+       * src/reader.c (symbol_typed_p): Add parens to pacify GCC.
+       * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): #undef yylloc and yylval
+       before #defining them.
+       * tests/glr-regression.at
+       (Incorrectly initialized location for empty right-hand side in GLR):
+       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'.
+
+2006-01-19  Akim Demaille  <akim@epita.fr>
+
+       * tests/calc.at (_AT_DATA_CALC_Y): Initialize the whole initial
+       location, not just parts of it.

        * NEWS: Document the fact that multiple %unions are now allowed.
