Happy new year! :)

I probably mentioned this in your MapServer thread: I did a lot of 
testing of outputformat on windows with MS4W, and you can follow along 
the discussion at http://trac.osgeo.org/mapserver/ticket/3751 - I 
believe those tests were with MapServer 6.2-dev.

Regarding temp file location problems: I have seen this reported 
recently for both linux and windows users.  However I did not hit those 
issues when testing ticket:3751

I think the best way forward would be to create a small test package, 
then make sure you can duplicate the problem with MapServer trunk 
(6.2-dev) on both Windows and Linux; then file the ticket in MapServer 
Trac.  Please CC me in the ticket.
