+
+ * data/bison.m4 (b4_percent_define_copy_, b4_percent_define_copy):
+ New.
+ (b4_percent_define_use): New.
+ Use it where applicable.
+ * data/c++.m4: Replace uses of the variable "namespace" by

+
+ deterministic test suite.
+ Some consistency checks on symbols are performed after all the
+ symbols were read, by an iteration over the symbol table. This
+ traversal is nondeterministic, which can be a problem for test

+
+ build: avoid ignored errors.
+ * doc/local.mk ($(CROSS_OPTIONS_TEXI)): Don't generate ignored

+ --force-define with %define.
+ * doc/bison.texinfo (Decl Summary): In %define entry,
+ cross-reference command-line options.
+ (Bison Options): Add documentation to -D/--define entry.
+ (Option Cross Key): Widen column for --force-define row.
+ * src/getargs.c (usage): Document -F/--force-define. Realign
+ options in output.
+ (short_options, long_options, getargs): Parse -F/--force-define,
+ and update muscle_percent_define_insert invocations.

+ * src/muscle-tab.h (muscle_percent_define_insert): Likewise.
+ (muscle_percent_code_grow): Likewise just for consistency.
+
+2009-05-20 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * data/c++.m4 (b4_namespace_close): Simplify slightly.
+
+2009-05-19 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Handle a trailing `:' in a user-supplied C++ namespace better.
+ * data/c++.m4 (b4_namespace_close): Don't let it be printed
+ among the closing braces here. This fix might make the
+ generated code easier to debug, but otherwise it should be
+ insignificant because a trailing `:' is a C++ error already.
+
+2009-05-19 Akim Demaille <demaille@gostai.com>
+
+ remove useless variable.
+ * src/getargs.c (skeleton_arg): Remove now useless variable.
+ Should help the compiler see that this printf-like call is sane.
+
+2009-05-15 Akim Demaille <demaille@gostai.com>

+
+ doc: token.prefix
+ * doc/bison.simple (Decl Summary): Document token.prefix.
+ (Calc++ Parser): Various fixes.
+ Formatting changes.
+ Use token.prefix.

+
+2009-05-04 Akim Demaille <demaille@gostai.com>

+ * tests/input.at: Adjust.
+
+2009-05-04 Akim Demaille <demaille@gostai.com>
+
+ identifiers: dashes are letters.
+ Dashes can now start identifiers (symbols and directives).
+
+ * src/scan-gram.l ({letter}): Add dash.
+ ({id}): Remove it.
+ * tests/input.at (Symbols): Adjust.
+ Remove stray comment.

+ * NEWS (2.5): Document.
+ * data/c.m4 (b4_identification): Update comment.
+ * data/yacc.c: Update access.
+ * doc/bison.texinfo: Update.
+ * etc/bench.pl.in (bench_push_parser): Update use.
+ * src/files.c (tr): Move to...
+ * src/getargs.c, src/getargs.h (tr): ... here because I can't
+ think of a better place to expose it. My logic is that, for all
+ uses of tr so far, command-line arguments can be involved, and
+ getargs.h is already included.
+ * src/main.c (main): Update access.
+ * src/muscle_tab.c (muscle_percent_define_insert): Convert old
+ variable names to new variable names before assigning value.
+ * src/reader.c (reader): Update setting default.
