I may be off the mark here, but IIRC, nfs-server is a pretty old package
and hasn't been updated in a while, so it may still be compiled against
the older versions of Cygwin that didn't have 64-bit IO.  Running nm on
the nfs-server executable (which I currently don't have installed, so
can't do this myself) should show whether I'm right.
