locale and pthreads do not work together

[jury gerold <gjury at grips dot com>]

The following little program fails on various versions of glibc + linux-threads
up to version 2.2.1

I regenerated all the locales, used localedef in various ways.
Nothing helps.
As soon as the pthreads library is involved, locales refuse to work for me.

Anyone with an idea what i am doing wrong ?

Best Regards

Gerold
