Use off_t when we really mean a file offset.
Not all platforms have declared 'unsigned long' to be a 64 bit value, but we want to support a 64 bit packfile (or close enough anyway) in the near future as some projects are getting large enough that their packed size exceeds 4 GiB. By using off_t, the POSIX type that is declared to mean an offset within a file, we support whatever maximum file size the underlying operating system will handle. For most modern systems this is up around 2^60 or higher. Signed-off-by: Shawn O. Pearce <spearce@spearce.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
