+
+ * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
+ rather than a for-loop that declares a local bool variable. This
+ should work around a compatibility problem with a Cray x1e C++
+ compiler reported by Hung Nguyen in
+ <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
+ The for-loop was introduced in the 2004-11-17 change but I don't
+ know why it was needed.

+ * data/c.m4: Comment changes.
+
+2006-07-10 Akim Demaille <akim@lrde.epita.fr>
+
+ * src/complain.c (error_message, ERROR_MESSAGE): New.
+ To factor...
+ (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
+ * src/complain.h, src/complain.c (warning_issued): Remove, unused.

+
+ * NEWS: Instead of %union, you can define and use your own union type
+ YYSTYPE if your grammar contains at least one <type> tag.
+ Your YYSTYPE need not be a macro; it can be a typedef.
+ * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
+ (Union Decl, Decl Summary): Document this.
+ * data/glr.c (YYSTYPE): Implement this.
+ * data/glr.cc (YYSTYPE): Likewise.
+ * data/lalr1.cc (YYSTYPE): Likewise.
+ * data/yacc.c (YYSTYPE): Likewise.
+ * src/output.c (prepare): Output tag_seen_flag.
+ * src/parse-gram.y (declaration, grammar_declaration):
+ Use 'union_seen' rather than 'typed' to determine whether
+ %union has been seen, since grammars can now be typed without
+ %union.
+ (symbol_declaration, type.opt, symbol_def):
+ Keep track of whether a tag has been seen.
+ * src/reader.c (union_seen, tag_seen): New vars.
+ (typed): remove.
+ * src/reader.h (union_seen, tag_seen, typed): Likewise.
+ * src/scan-code.l (untyped_var_seen): New variable.
+ (handle_action_dollar): Adjust to above changes.
+ (handle_action_dollar, handle_action_at):
+ Improve overflow checking for outlandish numbers.
+ * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
+ avoid new diagnostics generated by above changes.
+ * tests/regression.at (YYSTYPE typedef): Add test to check
+ for type tags without %union.
+
+ * src/symlist.c (symbol_list_length): Return int, not unsigned
+ int, since callers expect int. This may need to get revisited
+ once we have proper integer overflow checking.
+
+ * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
+ object is now static.
+
+ * src/getargs.c (flags_argmatch): Return void, not int,
+ to pacify ./configure --enable-gcc-warnings.
+
+ * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
+ since last_string is already defined to FLEX_PREFIX (last_string).
+

Implement --warnings/-W.
* data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
