[FWTools] Differences between Windows and Unix proj4?

[Kolberg Sjur A]

Dear list;
 
I am struggling with the re-projection of some data from the Norwegian met office (met.no). Through the process we have come to compare some simple test, transforming a point using the proj command in a console window. The met office has tried, with all of these versions:
 
Rel. 4.3.3, 23 Sept. 1995
Rel. 4.4.9, 29 Oct 2004
Rel. 4.5.0, 22 Oct 2006

and gets the projected position:

spiralis:~$ /usr/bin/proj +ellps=WGS84 +proj=stere +lat_0=90 +lat_ts=60 
+lon_0=0 -f '%.5f'
10.202 63.696
493913.51155 -2744506.20400

Whereas I get, with version  
Rel. 4.5.0, 22 Oct 2006, installed as a part of fwtools 1.2.2 or 1.3.1:

C:\Program Files\FWTools1.2.2>proj +ellps=WGS84 +proj=stere +lat_0=90 
+lat_ts=60 +lon_0=0 -f '%.5f'
10.202 63.696
'496554.53029' '-2759181.42981'


Are there some hidden defaults here, that might be different?
