I noticed some small discrepancies in cs2cs between Windows and Linux.

Version for both is "Rel. 4.8.0, 6 March 2012"

Command used:
cs2cs -f "%.17g" +proj=tmerc +lat_0=0 +lon_0=15 +k=1 +x_0=5500000 +y_0=0 
+ellps=bessel +datum=potsdam +units=m +no_defs +to +proj=utm +zone=33 
+ellps=WGS84 +datum=WGS84 +units=m +no_defs

Coordinates used:
5398786.5625 5672047.509765625

Result Windows:
398690.85663695924 5670224.1293941503

Result Linux:
398690.85663695924 5670224.1293941513

Difference is with 5670224.1293941503 in the second to last place.

Can anybody explain why this might be happening and what I could do 
about it?

Best regards,
