+
+       * src/scan-skel.l: Scan more than one inert character per yylex
+       invocation.
+
+2003-02-01  Paul Eggert  <eggert@twinsun.com>
+
+       Version 1.875a.
+
+       * po/LINGUAS: Add ms.
+
+2003-01-30  Akim Demaille  <akim@epita.fr>
+
+       * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
+
+2003-01-29  Paul Hilfinger  <Hilfinger@CS.Berkeley.EDU>
+
+       * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
+       of $1.
+
+       Changes in response to error report by S. Eken: GLR mode does not
+       handle negative $ indices or $ indices in embedded rules correctly.
+       See <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
+
+       * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
+       (b4_rhs_location): Ditto.
+       (yyfill): New function to copy from stack tree into array
+       incrementally.
+       (yyuserAction): Modify to allow incremental move of semantic values
+       to rhs array when in GLR mode.
+       Define YYFILL to use in user-defined actions to fill semantic array
+       as needed.
+       Remove dummy use of yystack, as there is now a guaranteed use.
+       (yydoAction): Modify to allow incremental move of semantic values
+       to rhs array when in GLR mode.
+       (yyresolveAction): Ditto.
+       (yyglrShiftDefer): Update comment.
+       (yyresolveStates): Use X == NULL for pointers, not !X.
+       (yyglrReduce): Ditto.
+       (yydoAction): Ditto
+
+       * tests/glr-regr1.at: Rename to ...
+       * tests/glr-regression.at: Add new regression test for the problems
+       described above (adapted from S. Eken).
+       Update copyright notice.
+       * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
+       * tests/Makefile.am: Ditto.
+
+2003-01-28  Paul Eggert  <eggert@twinsun.com>
+
+       * data/lalr1.cc: Do not use @output_header_name@ unless
+       b4_defines_flag is set.  This fixes two bugs reported by
+       Tim Van Holder in
+       <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
+       and <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
+
+2003-01-21  Paul Eggert  <eggert@twinsun.com>
+
+       * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
+       we don't need to worry about yyerrlab1 being reported as an
+       "unused label" by non-GCC C compilers.  The downside is that if
+       locations are used then a couple of statements are duplicated each
+       time YYERROR is invoked, but the upside is that the warnings
+       should vanish.
+       (yyerrlab1): Move code to YERROR.
+       (yyerrlab2): Remove.  Change uses back to yyerrlab1.
+       This reverts some of the 2002-12-27 change.
