+ clashes.
+ * src/scan-gram.l: Use [\'] instead of ['] to pacify
+ font-lock-mode.
+ Use complain_at.
+ Use quote, not quote_n since LOCATION_PRINT no longer uses the
+ slot 0.
+
+2002-11-03 Paul Eggert <eggert@twinsun.com>
+
+ * src/reader.c (get_merge_function, grammar_current_rule_check):

+
+2002-11-03 Paul Eggert <eggert@twinsun.com>
+
+ * src/scan-gram.l: Revamp to fix POSIX incompatibilities,

+ Include mbswidth.h.
+ (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
+ (extend_location): New function.
+ (YY_LINES): Remove.
+
+ Handle CRLF in C code rather than in Lex code.

+
+ ({int}, handle_action_dollar, handle_action_at): Check for integer
+ overflow.
+
+ (YY_STEP): Omit trailing semicolon, so that it's more like C.
+
+ (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
+ as well as \000. Check for UCHAR_MAX, not 255.
+ Allow \x with an arbitrary positive number of digits, as in C.
+ Check for overflow here.
+ Allow \? and UCNs, for compatibility with C.
+
+ (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
+ with quote slot used by complain_at.

+
+2002-10-30 Paul Eggert <eggert@twinsun.com>
+
+ * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
+ Check for close failures.

+ returned zero.
+ * src/files.c (xfclose): Likewise. Report I/O error if ferror
+ indicates one.

+ and ferror. xfclose now checks ferror.
+
+ * data/glr.c (YYLEFTMOST_STATE): Remove.

+ our continuing battles with bogus warnings about initializers.
+
+2002-10-30 Akim Demaille <akim@epita.fr>

+ Version 1.75a.
+
+ * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
+ * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
+ we use malloc. Don't assume 'A' through 'Z' are contiguous.
+ Don't assume strdup exists; POSIX says its an XSI extension.
+ Check for buffer overflow on input.
+
+2002-10-24 Akim Demaille <akim@epita.fr>
+
+ * src/output.c (output_skeleton): Don't disable M4sugar comments
+ too soon: it results in comments being expanded.
+ * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
+ first output.
+
+2002-10-24 Akim Demaille <akim@epita.fr>
+
+ * data/yacc.c (m4_int_type): New.
+ * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
+ char' as only yacc.c wants K&R portability.
+ * data/glr.c (yysigned_char): Remove.
+ * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
+ Reported by Quoc Peyrot.
+
+2002-10-23 Paul Eggert <eggert@twinsun.com>
+
+ * src/main.c (main): With --trace=time, report times even if a
+ non-fatal error occurs. Formerly, the times were reported in some
+ such cases but not in others.
+ * src/reader.c (reader): Just return if a complaint has been issued,
+ instead of exiting, so that 'main' can report times.
+
+2002-10-22 Akim Demaille <akim@epita.fr>
+
+ * src/system.h: Include sys/types.
+ Reported by Bert Deknuydt.
+
+2002-10-23 Paul Eggert <eggert@twinsun.com>
+
+ * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
+ Suggested by Art Haas.
+
+2002-10-22 Paul Eggert <eggert@twinsun.com>
+
+ * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
+ decl; not needed any more.
+ * src/main.c (main): Use return to exit, undoing yesterday's change.
+ The last OS that we could find where this wouldn't work is
+ SunOS 3.5, and that's too old to worry about now.
+
+ * data/glr.c (struct yyltype): Define members even when not
+ doing locations. This is more consistent with yacc.c, and it
+ works around the following bug reports:
+ http://mail.gnu.org/pipermail/bug-bison/2002-October/001764.html
+ http://mail.gnu.org/pipermail/bug-bison/2002-October/001769.html
+ and I hope it also fixes this bug report:
+ http://mail.gnu.org/pipermail/bug-bison/2002-October/001748.html
+
+ * doc/bison.texinfo: Minor spelling and typographical fixes. Use
+ @acronym consistently. Standardize on "Yacc" instead of "YACC",
+ "Algol" instead of "ALGOL". Give a bit more history about BNF.
+
+2002-10-22 Akim Demaille <akim@epita.fr>
+
+ * data/README: New.
+
+2002-10-21 Paul Eggert <eggert@twinsun.com>
+
+ Be consistent about 'bool'; the old code used an enum in one
+ module and an int in another, and this violates the C standard.
+ * m4/stdbool.m4: New file, from coreutils 4.5.3.
+ * configure.ac (AC_HEADER_STDBOOL): Add.
+ * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
+ * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
+ * src/symtab.c (hash_compare_symbol_t): Likewise.
+ * src/system.h (bool, false, true): Use a definition consistent
+ with ../lib/hash.c. All uses changed.
+
+ * src/complain.c (warning_issued): Renamed from warn_message_count,
+ so that we needn't worry about integer overflow (!).
+ Now of type bool. All uses changed.
+ (complaint_issued): Renamed from complain_message_count; likewise.
+
+ * src/main.c (main): Use exit to exit with failure.
+
+ * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
+ rather than 1 and 0.
+ * src/main.c (main): Likewise.

+ * src/reader.c (reader): Likewise.
+
+ * src/getarg.c (getargs): Remove duplicate code for
+ "Try `bison --help'".
+
+ * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
+ What was that "2" for?
+
+ * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
+ * src/getargs.c (usage): Likewise.
+
+ * src/getargs.c (getargs): When there are too few operands, report
+ the last one. When there are too many, report the first extra
+ one. This is how diffutils does it.
+
+2002-10-20 Paul Eggert <eggert@twinsun.com>
+
+ Remove K&R vestiges.
+ * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
+ * src/complain.c (VA_START): Remove. Assume prototypes.
+ (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
+ (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
+ fatal): Assume prototypes.
+ * src/complain.h: Assume prototypes.
+ * src/system.h (PARAMS): Remove.
+ Include <limits.h> unconditionally, since it's guaranteeed even
+ for a freestanding C89 compiler.
+ (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
+ * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
+
+2002-10-20 Akim Demaille <akim@epita.fr>
+

+ * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
+ (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
+ These.
+
+2002-10-19 Paul Eggert <eggert@twinsun.com>
+
+ Do not create a temporary file, as that involves security and
+ cleanup headaches. Instead, use a pair of pipes.
+ Derived from a suggestion by Florian Krohm.
+ * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
+ * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.

+ Read from stream rather than file.
+
+ * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
+ float, as this generates a warning on Solaris 8 + GCC 3.2 with
+ --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
+ this generates a more-accurate value anyway.
+
+ * lib/timevar.c (timervar_accumulate): Rename locals to
+ avoid confusion with similarly-named more-global.
+ * src/muscle_tab.c (muscle_pair_list_grow): Likewise.

+ Drop the `_' version of %glr-parser.
+ Add the "," token.
+ * src/scan-gram.l (INITIAL): Scan them.

+
+2002-10-19 Akim Demaille <akim@epita.fr>
+
+ * src/getargs.c (usage): Take status as argument and exit
+ accordingly.
+ Report the traditional `Try ... --help' message when status != 0.
+ (usage, version): Don't take a FILE * as arg, it is pointless.
+ (getargs): When there is an incorrect number of arguments, make it
+ an error, and report it GNUlically thanks to `usage ()'.
+
+2002-10-18 Paul Eggert <eggert@twinsun.com>
+
+ * data/glr.c (yyreportParseError): Don't assume that sprintf
+ yields the length of the printed string, as this is not true
+ on SunOS 4.1.4. Reported by Peter Klein.
+
+ * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
+ * tests/conflicts.at (%nonassoc and eof): Likewise.
+ Fixes SunOS 4.1.4 test failure reported by Peter Klein.
+
+2002-10-17 Akim Demaille <akim@epita.fr>
+
+ * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
+ * src/getargs.c (trace_types, trace_args): Adjust.

+
+2002-10-16 Paul Eggert <eggert@twinsun.com>
+
+ * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
+ MUSCLE_TAB_H.
+
