Pushed, thanks for that!
The problem was introduced during gbuild'ification of l10ntools module.
We changed it from wrapping to using the generated files directly
(we used ignore system header instead of diagnsoric pragma).

I extended your patch and added the "-w" option to hide these ugly flex 
I forgot it during gbuildi'ification ;-)

May I kindly ask you to use in future our new Code Review System gerrit:
instead of sending patches to dev ML?
You can find the infos how to register, configure and use it here:


If you have questions or want provide feedback, you can ask on ML
or catch gerrit guys on IRC: Sweetshark, shm_get and reinsle.
