No, it's not unused.  See the table near the documentation of function
6Ch: this flag is extended FAT32 open, it is needed to support opening
files that are larger than 2GB.

So it seems like Windows 2000 doesn't support FAT32, either in its LFN
API or at all.  Could you please set LFN=n and see if DJGPP.ENV can be
read, even without removing 0x1000 from the value of BX?

Anyway, thanks a lot for working on this, it seems like we can now
solve this bug, after you check what happens without LFN.
