+
+	* scan-gram.l (YY_USER_INIT): Initialize code_start, too.
+	(<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
+	cursor, instead of leaving it undefined.  This fixes a bug
+	reported by Tim Van Holder in
+	<http://mail.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
+	* tests/input.at (Torturing the Scanner): Test the scanner on
+	an empty input file, which was Tim Van Holder's test case.
+
+	* m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
+	<sys/resource.h> can be included, include sys/time.h and
+	sys/times.h first, if available.  This works around the SunOS
+	4.1.4 porting bug reported by Bruce Becker in
+	<http://mail.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
+
+	* m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
+	AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
+	AC_HEADER_SYS_WAIT.
+
+	Merge changes from gnulib.  This was prompted because the CVS
+	snapshot didn't build on Solaris 7 due to strnlen problems.
+
+	These changes need to be merged back into gnulib:
+	* lib/hash.c: Include <stdbool.h> unconditionally.
+	* m4/onceonly.m4 (m4_quote): New macro.
+	(AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
+	Quote AC_FOREACH variable-expansions properly.
+	The 2003-01-03 obstack.h change also needs merging.
+	{end of changes requiring merging}
+	
+	* lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,

+	m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
+	New files, imported from gnulib.
+	* m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
+	above.
+
+	* lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
+	m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
+	gnulib sources.
+
+	* configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
+	Add.
+	(gl_ERROR): New, replacing jm_PREREQ_ERROR.
+	(gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
+	(gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
+	(gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
+	(gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
+	(gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
+	(gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
+	(jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
+	(jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
+	(jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
+	(jm_PREREQ_ARGMATCH): Remove.
+	(AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
+	* lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
+
+	* src/system.h: Include <stdbool.h> unconditionally.
+
+	* lib/bbitset.h: Include <limits.h> unconditionally.  We have been
+	assuming at least C89 in the bitset code for some time now.
+
+2003-03-03  Akim Demaille  <akim@epita.fr>
+
+	* ro.po: New.
+
+2003-03-02  Akim Demaille  <akim@epita.fr>
+
+	* doc/bison.texinfo (Table of Symbols): Reactivate the
+	documentation for %lex-param, and %parse-param.
+
+2003-03-02  Akim Demaille  <akim@epita.fr>
+
+	* data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
+	generate verbose error messages.
+	Use the number of tokens as an upper bound in yytname, as it
+	cannot be a non terminal.
+
+2003-03-02  Akim Demaille  <akim@epita.fr>
+
+	* tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
+	message.
+
+2003-03-02  Akim Demaille  <akim@epita.fr>
+
+	* tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
+	Use them to exercise yycheck overrun.
+	Based on Andrew Suffield's grammar.
+
+2003-03-02  Akim Demaille  <akim@epita.fr>
+
+	Create tests/local.at for Bison generic testing macros.
+
+	* tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
+	* tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
+	This new file.
+	* tests/calc.at (AT_CHECK_CALC): Adjust.
+	* tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
+	(AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
+	* tests/local.at: here.
+	(AT_COMPILE_CXX): Tags the tests using it as c++.
+	Ignore the test if CXX is not functional.
+
+2003-03-01  Paul Eggert  <eggert@twinsun.com>
+
+	* src/scan-gram.l (code_start): Initialize it to scanner_cursor,
+	not loc->end, since loc->end might contain garbage and this leads
+	to undefined behavior on some platforms.
+	(id_loc, token_start): Use (IF_LINTed) initial values that do not
+	depend on *loc, so that the reader doesn't give the the false
+	impression that *loc is initialized.
+	(<INITIAL>"%%"): Do not bother setting code_start, since its value
+	does not survive the return.
+
+2003-03-01  Akim Demaille  <akim@epita.fr>
+
+	* src/scan-gram.l (code_start): Always initialize it when entering
+	into yylex, as SC_EPILOGUE is activated *before* the corresponding
+	yylex invocation.  An alternative would be making it static, but
+	then it starts with the second %%'s beginning, instead of its end.
+
+2003-02-28  Paul Eggert  <eggert@twinsun.com>
+
+	* lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
+	around a UnixWare 7.1.1 porting bug reported by John Hughes in
+	<http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
+
+2003-02-26  Paul Eggert  <eggert@twinsun.com>
+
+	* README: Mention compiler bug in Sun Forte Developer 6 update 2.
+	Remove Sequent/Pyramid discussion (nobody uses them any more).
+	Merge VMS and MS-DOS discussion; these ports may well be dead
+	but let's keep mentioning them for now.  Put <> around email
+	addresses.  Add copyright notice.
+
+2003-02-24  Paul Eggert  <eggert@twinsun.com>
+
+	* data/glr.c (yy_reduce_print): yylineno -> yylno,
+	to avoid collision with flex use of yylineno.
+	Problem reported by Bruce Lilly in
+	<http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.
+	* data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
+	* data/yacc.c (yy_reduce_print): Likewise.
+
+	* config/depcomp: Sync with Automake 1.7.3.
+
+2003-02-21  Akim Demaille  <akim@epita.fr>
+
+	* data/lalr1.cc: Use temporary variables instead of casts to
+	change integer types.
+	Suggested by Paul Eggert.
+
+2003-02-21  Akim Demaille  <akim@epita.fr>
+
+	* doc/bison.texinfo: Use "location" consistently to refer to @n,
+	to avoid confusions with lalr1.cc's notion of Position.
+	Suggested by Paul Eggert.
+
+2003-02-20  Akim Demaille  <akim@epita.fr>
+
+	* data/lalr1.cc (position.hh): Make sure "columns" never pushes
+	before initial_columns.
+	(location.hh): Use consistent variable names when defining the
+	operator<<.
+	Use "last" so that we subtract from Positions, not from unsigned.
+
 2003-02-20  Akim Demaille  <akim@epita.fr>
 
 	* data/lalr1.cc (position.hh): New subfile, including the extended
 	and Doxygen'ed documentation of class Position.
 	(location.hh): Use it.
 	Document a` la Doxygen.
