Subject:      Will DJGPP work in an OS/2 DOS session?

Is there any way to get DJGPP to run in a DOS session under OS/2?  So far, I
haven't been able to make it work on my machine.  I get a trap, with this
error:

   SYS2237: DosKrnl: A NPX instruction was attempted, but no NPX is present.
   EXPLANATION: You have an application attempting to use the numeric
   coprocessor, but no coprocessor is present on this system.
   ACTION: Install a numeric coprocessor and retry the application.

My PC indeed had no coprocessor.  If I boot the same PC with DOS (6.3), I can
run the demo makefile OK.  I'm using the same environment settings in both
cases (including "GO32=EMU D:\H8300H\GNU\BIN\EMU387").

Can anyone explain?  Can anyone suggest a solution?  With OS/2, I have a fair
amount of latitude in changing settings for the DOS environment.

I should mention that I've tried in two fundamentally different DOS
environments.  I've run in the native OS/2 DOS session, and I've also set up
a session in which real DOS 6.3 is booted in its own session.  Both fail in
the same manner.
