mozcommitbuilder adds with mozconfig option for Windows builds: ac_add_options --with-windows-version=600 Starting with this changeset http://hg.mozilla.org/mozilla-central/rev/3950aa85276d the windows version must be 601, later 602 (Windows 8) has been allowed, too: http://hg.mozilla.org/mozilla-central/rev/19f1387c2402. I suggest to use 601 for compatibility reasons.
