486SX doesn't have an FPU (IIRC), so you do need the emulator. The
fact that you need to set 387=YES probably means that auto-detection
somehow fails to work.

That sounds wrong, unless it's a typo. You need to have
"emu c:\djgppv1\bin\emu387" in the GO32 variable, note the "bin" part.
> I assume that emu387 is working otherwise I would have compile problems.
Probably. You could try compiling and running a small program that
does FP math, to be sure.

You don't need that directory, only the file djgppv1\bin\emu387, which
is the pre-compiled emulator.
I cannot help you with the other questions.
