Hello Bruno,

thanks a lot for the pointers to help. A follow-up question:

Thanks for pointing this out. What I didn't know (and from the arguments isn't 
obvious) is that --keyword or -k is necessary to switch off the default 
keywords. (It might be worthwhile to consider an additional 
argument --no-default-keywords to make this much more obvious.) However, when 
using this as described and using only our aliases for gettext and 
gettext_noop, i.e.

  xgettext --k --keyword=_ --keyword=N_ ...

it turns out I forgot the ngettext() calls. Hence, I used

  xgettext --k --keyword=ngettext --keyword=_ --keyword=N_ ...

*However*, when specifying ngettext here, it turns out xgettext doesn't 
recognize the special argument semantics of ngettext anymore. Instead of 
extracting both the msgid and the msgid_plural, with the above form I only 
get the msgid and the string isn't marked as a ngettext message anymore. Any 
hints for here? (I'm using gettext 0.15, a version which is probably used by 
many of my fellow developers)

Thanks for the proposal. This one is probably the way to go.
