+
+ Clean up %define and %code implementation in M4 some. Most
+ importantly, rename all related macros to be in the b4_percent_define
+ and b4_percent_code namespaces. Also, complete support for `.' in
+ %define variable names and %code qualifiers.
+ * data/bison.m4 (b4_check_user_names): Check for special
+ "SKELETON-NAMESPACE(name)" macros instead of using two nested
+ m4_foreach loops.
+ (b4_get_percent_define, b4_get_percent_code): Rename to...
+ (b4_percent_define_get, b4_percent_code_get): ... these.
+ Extend documentation with examples.
+ For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
+ b4_percent_define_skeleton_variables and
+ b4_percent_code_skeleton_qualifiers.
+ Expect any value for the %define variable `foo' to be stored in the
+ macro named `b4_percent_define(foo)'; expect any %code blocks for the
+ qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
+ expect any unqualified %code blocks to be stored in a macro named
+ `b4_percent_code_unqualified'.
+ Use m4_indir so that %define variable names and %code qualifiers can
+ contain `.', which is allowed by the grammar parser.
+ (b4_percent_define_default): New macro to set a default value for a
+ %define variable.
+ (m4_wrap): Update wrapped code, and fix some underquoting.
+ (b4_check_user_names_wrap): Update and define outside the m4_wrap.
+ Expect grammar uses of %define variables and %code qualifiers to be
+ defined in b4_percent_define_user_variables and
+ b4_percent_code_user_qualifiers.
+ * data/c++.m4: Use b4_percent_define_default rather than
+ m4_define_default. Fix some underquoting. Skeleton usage of %define
+ variable define_location_comparison now implies skeleton usage of
+ %define variable filename_type.
+ * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
+ data/push.c, data/yacc.c: Update macro names.
+ * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
+ muscle names.

+ DJGPP specific issues.
+
+ * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
+ default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
+
+2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
+ run parsers in all tests so that Valgrind is invoked during
+ maintainer-check-valgrind.
+ (Duplicate representation of merged trees): Free all semantic values.
+ (Duplicated user destructor for lookahead): Likewise.
+
+2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
+ command-line prefix.
+ * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
+ ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
+ miss Valgrind messages.
+ (Exploding the Stack Size with Malloc): Likewise.
+
+2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
+ locals. Reported by Juan Manuel Guerrero at
+ <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
+ * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
+ Fix some indentation also.
+ * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
+ explaining this issue.

* src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
than prologue_augment for prologue parsing so you don't need prologue
obstacks.
- (grammar_declaration): Use `braceless' instead of "{...}" so that
- braces are already stripped and code is escaped with digraphs.
+ (grammar_declaration): For %union RHS, use `braceless' instead of
+ "{...}" so that braces are already stripped and code is escaped with
+ digraphs.
* src/reader.c (prologue_augment): Remove.
(reader): Remove initialization of pre_prologue_obstack and
post_prologue_obstack.
b4_check_percent_code_qualifiers. Use b4_get_percent_code.
* data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
(b4_parser_class_name, b4_namespace): Define these using
- b4_get_percent_define for parser_class_name and namespace. Normally
- this would be a bad idea since there might be cases when the variables
- aren't used, but these variables are too pervasive in these skeletons
- for that to be a problem.
+ b4_get_percent_define for parser_class_name and namespace.
* data/location.cc: Use b4_get_percent_define.
* data/push.c: Don't use b4_check_percent_define_variables and
b4_check_percent_code_qualifiers. Use b4_get_percent_code.
* data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
m4_divert_push(0) and m4_divert_pop(0).
- * data/output.c (output_skeleton): Don't add an m4_divert_push(0) and
+ * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
pushed and popped by m4sugar, should be first on the stack.
