There are also some changes that need to be done to libmv but I'm leaving those out so I can get it patched upstream first. (Only works with gcc/g++ if we want to use sun's compiler we would need to get rid of all of our annonymous structs which I don't think we want to do at this point, example: typedef struct wmNDOFMotionData { union { float tvec[3]; // translation struct { float tx, ty, tz; }; // this would need to be fixed // something like this or something similar: struct { float x, y, z; } t; }; ... ) Kent
