I found this problem causes after the commit:

commit 532b91d24e9496c7988b2b1dda7fc0e8b161f782

    Cygwin: Make sure newer apps get uname_x even when loading uname dynamically

    if an application built after API version 334 loads uname dynamically,
    it actually gets the old uname, rather than the new uname_x.  Fix this by
    checking the apps API version in uname and call uname_x instead, if it's
    a newer app.

Reverting this commit solves the issue.

Corinna, could you please have a look?
