+
+       * data/yacc.c: (b4_lex_param): Corrected for the case where
+       %lex-param is provided and %pure-parser isn't.
+
+2003-04-27  Paul Eggert  <eggert@twinsun.com>
+
+       Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
+       <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
+       * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
+       if it is not defined.
+       (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.

+
+       * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
+       Declare to be of type suitable for the ninf value itself, not of
+       type suitable for the corresponding table, since the latter might
+       be unsigned but the ninf value might be negative.  This fixes a
+       bug reported by Alexandre Duret-Lutz in
+       <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
+
+       * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
+       invokes it.  We shouldn't invoke it twice because it will attempt
+       to put error.o in the archive twice.  This fixes a glitch reported
+       by Martin Mokrejs in
+       <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
+
+2003-04-21  Paul Eggert  <eggert@twinsun.com>
+
+       * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
+       to gnulib.
+
+2003-04-21  Yakov Markovitch <Markovitch@iso.ru>
+
+       * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
+       Fix obvious typo that results in uncompilable GLR parsers
+       when both %pure-parser and %locations are used.  (trivial change)
+
+2003-04-17  Paul Eggert  <eggert@twinsun.com>
+
+       * src/scan-gram.l: Add %option nounput, since we no longer use unput.
+       (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
+       Do not insert the expected token via unput, as this runs afoul
+       of a POSIX-compatibility bug in flex 2.5.31.
+       All uses changed to BEGIN the parent state,
+       since we no longer insert the expected token via unput.
+       * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
+       that is no longer emitted after the above change.
+
+       * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
+       the first one.  This change is from Paul Hilfinger, and it fixes
+       regression reported by Werner Lemberg in
+       <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
+
+       (resolve_sr_conflict): Don't invoke state_errs_set
+       unless one or more tokens have been explicitly made errors.
+       Otherwise, the above change causes Bison to abort.
+
+       * tests/existing.at (GNU pic Grammar): New test case, taken from
+       Lemberg's email.

        * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
