I don't understand why this comes up again. This was discussed here:

http://lists.blender.org/pipermail/bf-committers/2008-February/020248.html

and Campbell committed a subset of my patch for bug #6811 (see 
patchtracker),

http://svn.mandriva.com/cgi-bin/viewvc.cgi/packages/cooker/blender/releases/2.44/6.20070912.1mdv2008.0/SOURCES/blender-2.44-bug6811.patch?revision=84806&view=markup

long time ago, so why it needs again the forcing of 64bit offset?
