ndis fails to compile with netbsd-5

[Michael Litchard <michael%schmong.org@localhost>]

I took a look at doc/CHANGES-5.1 and my understanding is that ndis
should now compile
Here's my uname

NetBSD lucius.nexus.org 5.0_STABLE NetBSD 5.0_STABLE (GENERIC) #0: Sat
Sep 19 05:32:19 UTC 2009

amd64


What can I do to troubleshoot this problem?
