Doesn't this mean the produced GnuTLS will refuse to run on XP and
older, even if the NCRYPT functionality is not used at all, because it
will be linked against ncrypt.dll?  If so, I don't think this is the
right fix; instead, GnuTLS should load ncrypt.dll dynamically, when
needed, and call the functions from there via pointers.
