Try to add a line 
     SET 387=NO
in your autoexec.bat file if you don't have a math coprecessor on your 
computer. 

I once had the same problem as your and it disapeared after I add 
the above line. It seems to me that something like
    EMU387=%DJDIR%/bin/emu387.dxe
is not needed in djgpp.env file.
