+ tests: skip tests of file names that platform does not support.
+ Reported by Michael Raskin at
+ <http://lists.gnu.org/archive/html/bug-bison/2009-09/msg00001.html>.
+ * THANKS (Michael Raskin): Add.
+ * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Fix. Cygwin used
+ to fail at least for file names containing ":" or "\".

+
+ 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 (%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 (%error-verbose and YYSTACK_USE_ALLOCA):
+ New test group.
+ (%error-verbose overflow): New test group that reveals an
+ obscure bug. Expected fail for now.
+
+2008-12-11 Akim Demaille <demaille@gostai.com>
+
+ Pass the token type to yysyntax_error.
+ * data/yacc.c (yysyntax_error): Take the transated token instead
+ of the raw number.
+ Adjust callers.
+
+2008-12-11 Akim Demaille <demaille@gostai.com>
+
+ Simplify the i18n of the error messages.
+ * data/yacc.c (yysyntax_error): Rewrite, using a switch instead
+ of building dynamically the format string.
+
+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.

+
+ 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.

+
+2009-09-13 Joel E. Denny <jdenny@clemson.edu>
+
+ tests: clean up push.at test group titles.
+ * tests/push.at: Remove "Push Parsing: " from test group titles
+ because these are already under the banner "Push Parsing Tests".
+
+2009-09-12 Alex Rozenman <rozenman@gmail.com>
+
+ Provide an additional sub-message for clarity.
+ Add "symbol not found in production" error message when

+2009-09-10 Joel E. Denny <jdenny@clemson.edu>
+
+ Clean up yacc.c a little.
+ * data/yacc.c: Clean up M4 for readability, and make output
+ whitespace more consistent. For the main parse function
+ comment, instead of saying "yyparse or yypush_parse", say either
+ "yyparse" or "yypush_parse" depending on which it actually is.

+ Paul Eggert's explanations in the mailing lists.
+
+2009-09-05 Alex Rozenman <rozenman@gmail.com>
+
+ Use "Unresolved reference" error message when no symbols were found
+ in a symbolic reference resolution. Remove .expr and -expr from
+ the shown reference when the reference is unresolved.
+ * src/scan-code.l: Change the error message, adjust location columns,

+ * src/scan-code.h (code_props_rule_action_init): Rename
+ named_ref arg to name so it doesn't shadow named_ref type. This
+ makes it consistent with the function definition in scan-code.l
+ anyway.
+
+2009-08-28 Joel E. Denny <jdenny@clemson.edu>
+

+ Avoid compiler warning.
+
+2009-08-27 Joel E. Denny <jdenny@clemson.edu>

+ tests: use perl for printing special sequences to files.
+ And skip tests if perl is not available. This is better than
+ playing tricks with shell portability. Suggested by Akim
+ Demaille.
+ * tests/input.at (Bad character literals): Use it here for
+ omitting final newlines.
+ (Bad escapes in literals): Use it here for special characters.
