Umm... AFAICS, native Minix v3 fsck will throw a fit if it sees anything between 2Gb and 4Gb and truncate the value. Seeing that it's their format _and_ silent changes like that (especially hidden by something like "you need to binary-patch the field at this offset in superblock first") are generally considered rude.
I'd suggest you to talk to Minix folks and convince them to raise that limit; if it's merely a matter of unhappy fsck, it shouldn't be hard, but if their minix/mfs/*.c code would get unhappy on files longer than 2Gb, it would be harder and in that case we _really_ shouldn't run around creating such files there.
Seriously, talk to Minix folks first.
