Well, I think that we (or whoever that do it) don't even try to merge our host.def to the main trunk, it has nosense. I think that I will update the CVS branch this night. There aren't very important changes, but I think that it's better to have the branch as updated as possible. _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
