That is the aimed goal.

As noody has maintained that version in KDE (e.g. see the hash compatibility 
problem), I suppose that it will not get maintained in future either. So I 
think that a full switching to the Gettext runtime is better (even if 
perhaps, as first step, the run time would be provided still by kdelibs).

But isn't things that KDE has to do in one way or another too?

I would very much like to avoid to keep this KDE-specific plural form, even 
more if the PO files needs the Gettext formula anyway.

As for BC, as it is KDE4, we do not care much. (It is just a problem with the 
kdelibs snapshot.)

If you have that (even if not completely finsihed), please add it to 

Have a nice day!
