+       gnulib-tool: Make warning diagnostics consistent.
+       * gnulib-tool (func_warning): New function.
+       Use it everywhere where gnulib-tool produces output to stderr and it is
+       not a fatal error.
+
+2010-01-25  Bruno Haible  <bruno@clisp.org>
+
        Fix test dependencies.
        * modules/xstrtol-tests (Depends-on): Add inttypes.
        * modules/xstrtoll-tests (Depends-on): Likewise. Remove xstrtoll.
