Hi!

Willi has noticed a problem with the 4 GB file size limit:

If you use COPY x + y z style commands to concatenate files,
the FreeDOS kernel will fail to notice 32-bit offset overflows.

So your target file grows to 4 GB. It does not grow further.
BUT extra data will end up at the intended offset MODULO 4 GB.

Instead, the kernel should reject the attempt to write > 4 GB.

Regards, Eric
