Request for help building LO on Windows - unistd missing errors

Hi,

(I'm not sure this list is the right venue - please tell me if it isn't.)

In the hopes of implementing this missing feature:
https://bugs.freedesktop.org/show_bug.cgi?id=55436

I'm trying to build LO on Windows (XP). I seem to have downloaded 
everything necessary, passing the autogen and with make starting to 
work. But I'm stuck building nss, where I get errors regarding a missing 
unistd.h while building soltools.

My build log can be found at:

http://www.technion.ac.il/~eyalroz/content/build.log-2012-10-05_01.gz

My autogen.sh cmdline is:

 ./autogen.sh  --with-dotnet-framework-home="/cygdrive/c/Program 
Files/Microsoft SDKs/Windows/v7.0A" 
--with-mozilla-build="/cygdrive/k/mozilla-build" 
--with-ant-home="/cygdrive/k/lo/dls/apache-ant-1.8.4" 
--with-junit=/cygdrive/k/lo/dls/junit-4.10.jar" --without-help 
--without-myspell-dicts

Any help/reference to somewhere I could get help would be appreciated.

Eyal
