It still doesn't.  (It hasn't changed, to my knowledge.)

If you want an emulator that should work properly, get the
Intel-written one from Mach 3.0.  It's supplied as a binary (sources
are proprietary), but if you look at Mach's fpe_linkage.c and trap.c
you should be able to see what needs to be done.

Before I lost my PC, I considered doing this myself.
