gtk+ app don't replace gettext message

[Andreas Bachmann <bachi te-clan ch>]

hi!

I would like to develope a small gtk+ application, which should have
been i18n able.
But gettext don't replace the key (msgid) with the value (msgstr).
My gettext package and my localdir are set and running.
Could you please look at my source and my gnu autotools config?
