Ok, thank you very much for the explanation, I got it now and found a 
Solaris related gettext problem.

I guess it was already late yesterday :-(

"at" is not a valid locale name, so we don't need an alias for that.

Your patch didn't enable de_AT as a possible locale, but made de_AT an 
alias to de_DE. Thus it's completely irrelevant if you have de_AT 
locales installed on your system, you need to have the de_DE locales 
installed. But then again, this alias wasn't necessary because de_AT 
is already automatically set as an alias to de_DE in the locale 
selection code.

hmm, sorry for my ignorance.. now I'm getting a bit confused and I'm 
not sure what you mean by "not valid":

[didi@gollum ~]$ locale -a | grep de_AT

de_AT

de_AT@euro

de_AT.iso88591

de_AT.iso885915@euro

de_AT.utf8



I can set it as preferred language in almost any browser/OS, and at 
least at our installation without this alias the Umlauts are not 
getting displayed correctly in an automated manner, if someone has set 
the browser locale to de_AT.



Could you please put some light onto it? Thanks.

de_AT is already matched to de_DE and at is not a valid language code.
