This would preclude us from using 71A6h on Windows 2000, or on any
other system with an LFN TSR installed.  Is that justified?

I'd simply use _USE_LFN and drop the DOS version check.

Everything else looks okay to me, including changes to errno.h and the
library reference (except that there's one place where there's one
space after a dot ;-).

Btw, since even on FAT32 the largest file size fits into 32 bits, when
do we expect to get EOVRFLOW?  For networked drives?
