Subject: 387 emulation only when needed

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.
