How does djgpp check for LFN support, and how does it decide to use
short file names?  Do all the INT 21/AX=0x71xx functions need to be
supported, or just some critical few?

I'm asking because I'm mucking about with an asm-level LFN TSR for a
pure DOS 5.0 + djgpp environment.  I thought I would implement all the
TSR infrastructure first, and just reflect any INT 21/AX=0x71xx calls
back to their SFN equivalents.  Later I'll start adding the LFN support.
