   I've compiled a floating point program with the 387 emulator

	   (I've appended this in the autoexec.bat)
	   SET 387=QUERY
	   SET GO32=emu c:\c\djgpp\bin\emu387

   in a 486 DX2-66 PC, and its performance is 100 times worst than with the real
   coprocessor (I'm not complaining).

   The question is: How must I compile a program for been capable of running
   in both a PC with 387 using the real coprocessor, and in a PC without 387,
   but with emulator?

	   Thanks in advance.

You just did!  Users with a co-processor will not include the "emu" parameter
in the GO32 environment variable, those without will.  You need to distribute
emu387 along with go32 with your app.
