Yup, I guess you're right, Dave. What a pity we didn't spot it when we
introduced wide file handles. I hardly dare mention this ;-) but in
order to avoid breaking existing stuff, we appear to be looking at yet
another set of functions along the lines of OSArgs_ReadPtrWU. Hmm...

How serious is the problem? Do any current filing systems allow 32-bit
extents? I think it was yourself who raised the prospect of a complete
rewrite of FileCore in the future. This would undoubtedly change many
interfaces, and maybe an update is best left 'till then.

Anyone else have any thoughts on the matter?
