Yes, I know.  I wrote some of those "low-level file-oriented primitives".

Did you see who wrote that FAQ?

That's not the issue, you misunderstood my comment.  The issue is that
DJGPP programs switch the CPU to 32-bit protected mode, and use a DPMI
server to issue real-mode DOS and BIOS system calls from protected
mode.  doslfn seems to have problems with such programs (which is not
surprising, since any TSR that hooks interrupts might have problems in
protected mode).
