The point of such changes would be to lift this barrier at some point, which is what the other thread I am mentioning upthread is also pointing at. It does not change the fact that this code is currently not portable as written: off_t can be 4 or 8 bytes depending on the environment, and pgoff_t exists to be a stable alternative. This relates as well to the use of long in the tree, all coming down to WIN32. -- Michael
