Sorry, I don't understand the question.  Given the right software,
_any_ of the platforms DJGPP can run on could support the LFN API.
But in practice, some of them don't have the necessary software.
Plain DOS is one; DOSEmu is another; some old network redirectors and
OS/2 are yet another example.

This is not how _use_lfn works: you _can_ force it to query the
filesystem again if you call _use_lfn with a non-NULL argument.

In what situations would this option be useful?  If the callee is
expected to be able to cope with the LFN API calls, then why can't it
just support function 71A0h and return the LFN supported flag when we
call it?
