Hi Robert,
Philip was right on track and attached is the proof.
I tried to build it on WinXP some days ago and succeeded with a few
tweaks to the cmake files. Not sure if you are interested or where you
are going with osgEphemeris in svn but will submit the changes and let
you decide.
cheers
Mattias
