I don't think it applies to those xxx64 64bit offset I/O functions. If
I get it right, you can have a port with wordsize == 32bit, but 64bit
off_t. Basically, the size of off_t may not be the same as wordsize.
And the new port should use 64bit off_t even if the hardware is 32bit.
Did you try to say sysv/linux/off_t-64 and sysv/linux/off_t-32, or
something like it?
