Subject: libm on 386SX whithout 387 - HOW?

Hi, folks!
==========

One more question about support of old systems...

HOW CAN I EMULATE A 387 FLOATING POINT UNIT?

In the djgpp documentation I found that programs linked using -lm for sin or 
cos can only run on true 386DX or 386SX with 387SX - but how can I emulate 
a floating point unit on a 386SX without 387? Is there a publicly available
program to make libm believe that my computer knows how to compute sin and 
cos? - Funnily enough that the same executable that crashes on a 386SX 
runs fine on a 386DX without 387 !

                   Thanx in advance, Your's Sven. -
