cygwin started speaking German today

[Voelker, Bernhard]

Starting with today's update, cygwin started speaking German:

$ mkdir -v x0
mkdir: Verzeichnis „x0“ angelegt
$ LANG=C mkdir -v x2
mkdir: created directory `x2'
$ LANG=C.UTF-8 mkdir -v x1
mkdir: Verzeichnis „x1“ angelegt

Default is LANG=C.UTF-8 here.

Ok, the PC is in Germany, but none of my environment
variables have a 'de' inside.

Any hints?

Thanks & have a nice day,
Berny
