The code changed quite a bit in the meantime.  Your patch was against
Cygwin 1.5.x, so there's IPv6 support, native 64 bit support, dropped
support for older OS versions prior to XP SP3, etc.

But there are certainly still good chances for optimization.  I would
very much appreciate if you would take another look into this.
