Nut upsdev - Jan 2011 - windows_port branch does not compile on Ubuntu

I did a quick check to see if the windows_port branch still compiles  
on Ubuntu:

http://buildbot.networkupstools.org/public/nut/builders/Ubuntu-lucid-x86/builds/117/steps/compile/logs/stdio

Looks like there may be a mismatched #ifdef, or something similar.

I understand that this branch is experimental; however, if you merge  
from the trunk, I would recommend that you take that opportunity to  
check that things still build on the usual configurations.
