+
+ -F/--force-define and relative %define/-D/--define priorities.
+ * NEWS (2.5): Add documentation to -D/--define entry.
+ * build-aux/cross-options.pl: Hard-code association of

+
+ 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

+ 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.

+ * 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.
