--- Comment #7 from Zhenya Zenitur@yandex.ru --- It's really GnuTLS 2.4.1 in my SLES 11. Thank you, Kol!
In my build log (attached in dublicate bug) there is a configure output string:
configure: libgnutls 64-bit development files too old, bcrypt encryption won't be supported.
So, old GnuTLS isn't using by Wine anyway.
