True.

_USE_LFN was probably used to "test" for support of 0x71A6 since Windows
98/SE supports that function.  However, 71A6h and other LFN functions are
not
implemented by the various LFN drivers for DOS.


I tested _some_ of the LFN functions that were supported by different
drivers some years ago.

These are the functions I tested (unsorted):
710D, 71A0, 7139, 713B, 7147, 71A8, 716C, 7160, 5704, 5705, 5706, 5707,
71A6, 714E, 714F, 71A1, 7156, 7141, 71AA, 713A

Win98 supports all of those and likely some others.

Of the test list of functions above, DOSLFN and LFNDOS do not support these:
710D, 71A6, 71AA, 5706, 5707

So, those should all have checks.  It seems I did not check StarLFN ...

My notes (unconfirmed) say that DJGPP v2.03 calls all of those in the test
list, except for these two:
5707, 71AA

DJGPP also calls this one, so it should have a check too:
7143

Probably Win98 only:
71A7, 71A9

HTH,
