+ portability: fix several issues with M4 subprocess.
+
+ M4's output pipe was not being drained upon fatal errors during
+ scan_skel. As a result, broken-pipe messages from M4 were seen
+ on at least AIX, HP-UX, Solaris, and RHEL4, and this caused a
+ failure in the test suite. The problem was that, on platforms
+ where the default disposition for SIGPIPE is ignore instead of
+ terminate, M4 sometimes saw fwrite fail with errno=EPIPE and
+ then reported it. However, there's some sort of race condition,
+ because the new test group occasionally succeeded.

+ Fix handling of yychar manipulation in user semantic actions.
+ The problem was that yacc.c didn't always update the yychar

+ (excluded_files): Remove m4/printf-posix.m4.
+ * tests/atlocal.in (LIBS): As for LDADD in src/local.mk, add

+ of char*.
+ (Sbitset__isEmpty): Use Sbitset instead of char*.
+ * src/Sbitset.h (Sbitset): Make it a pointer to unsigned char
+ instead of char. This helps to avoid casting errors.
+ (Sbitset__or): Use Sbitset instead of char*.
+
+2009-10-16 Joel E. Denny <jdenny@clemson.edu>
+

+
+2009-09-23 Joel E. Denny <jdenny@clemson.edu>
+
+ yysyntax_error: avoid duplicate lookahead collection.
+ Except when memory reallocation is required, this change
+ eliminates the need to invoke yysyntax_error twice and thus to
+ repeat the collection of lookaheads. It also prepares for
+ future extensions that will make those repetitions more
+ expensive and that will require additional memory management in
+ yysyntax_error. Finally, it fixes an obscure bug already
+ exercised in the test suite.
+ * data/yacc.c (yysyntax_error): Add arguments for message
+ buffer variables stored in the parser. Instead of size, return
+ status similar to yyparse status but indicating success of
+ message creation. Other than the actual reallocation of the
+ message buffer, import and clean up memory management code
+ from...
+ (yyparse, yypush_parse): ... here.
+ * tests/regression.at (parse.error=verbose overflow): No longer
+ an expected failure.
+
+2009-09-23 Joel E. Denny <jdenny@clemson.edu>
+
+ yysyntax_error: test memory management more.
+ * tests/atlocal.in (NO_WERROR_CFLAGS): New cpp macro.
+ * tests/regression.at (parse.error=verbose and
+ YYSTACK_USE_ALLOCA): New test group.
+ (parse.error=verbose overflow): New test group that reveals an
+ obscure bug. Expected fail for now.
+
+2009-10-04 Joel E. Denny <jdenny@clemson.edu>
+
+ benchmarks: use %debug consistently among grammars.
+ * etc/bench.pl.in (generate_grammar_triangular): Do not activate
+ %debug by default. It can affect the timings even if yydebug=0.
+ (generate_grammar_calc): For consistency with other grammars,
+ use YYDEBUG environment variable to set yydebug.
+
+2009-10-03 Joel E. Denny <jdenny@clemson.edu>
+
+ Remove dead code.
+ * src/symtab.c (symbol_pack): Here because every symbol's number
+ is always defined by this time.
+
+2009-10-03 Alex Rozenman <rozenman@gmail.com>
+
+ Add additional space after periods in NEWS.
+ * NEWS (2.5): here.
+
+2009-09-29 Joel E. Denny <jdenny@clemson.edu>
+
+ Use the correct conversion specifier for size_t.
+ Reported by Jim Meyering.
+ * src/Sbitset.h (SBITSET__INDEX__CONVERSION_SPEC): New, "zu"
+ because Sbitset__Index is size_t.
+ * src/Sbitset.c (Sbitset__fprint): Use it instead of %d.
+
+2009-09-27 Joel E. Denny <jdenny@clemson.edu>
+
+ tests: don't abuse AT_BISON_CHECK.
+ * tests/regression.at (parse-gram.y: LALR = IELR): Move
+ additional shell commands outside of AT_BISON_CHECK.
+
+2009-09-26 Joel E. Denny <jdenny@clemson.edu>
+
+ tests: check that parse-gram.y's IELR and LALR are identical.
+ * tests/atlocal.in (abs_top_srcdir): New shell variable.
+ * tests/regression.at (parse-gram.y: LALR = IELR): New test
+ group.

+ * data/c++.m4, data/lalr1.cc (parser::symbol_type): Change the
+ constructor to take a token_type instead of the (internal) symbol
+ number.
+ Call yytranslate_.

+ because these are already under the banner "Push Parsing Tests".
+
+2009-09-12 Alex Rozenman <rozenman@gmail.com>
+

+ comment, instead of saying "yyparse or yypush_parse", say either
+ "yyparse" or "yypush_parse" depending on which it actually is.
+
