[Proj] Finnish KKJ in proj 4.4.9 - Linux vs. Windows

I have sorted out using proj 4.4.9 to obtain KKJ X/Y values from WGS84
LAT/LONG values.

To be more precise, I have this sorted out on Linux. I compiled the same
4.4.9 code on Windows using MS VC++ 6.0 and the makefile.vc in the proj
source. The problem is that I do not get the same results on the two
systems! The error is in the neighborhood of 100 meters.
Has anyone used proj on Windows and had any such problem? I have used
other similar libraries on both platforms before, so I did not expect

I was thinking of trying the 4.4.6 binary that is available for
downloads, but it does not contain a proj.lib file, making linking
problematic. Any reason there is not a windows binary of 4.4.9, and only
of 4.4.6?
