>Description:
I've upgraded mtools to version 4.0.10. It still can not handle FAT partitions bigger then 4GBytes due to copmarision of 8-byte off_t variables to 4-byte size_t limits.
 
 Copying to FAT partitions with mtools fails with "Big disks not supported on this architecture" error if FAT partition is bigger then 4G.

 Attached patch fixes this problem (from ports/132697)
