Actually, this is quite normal.  It will always happen with code which
calls _farptr functions to access _dos_ds on the application level
(library functions use a special variant of _farptr functions that
uses GS instead of FS). 

Since that was a v2.01 executable, _dos_ds has a limit of 4GB.  v2.02 
sets _dos_ds to 1MB+64KB limit instead.

No, nearptr works in Windows 9X; it's NT that fails it.

However, Emacs doesn't use nearptr at all.
