I've cross-posted to the Mach group in case anyone has any idea. Note that the comments at the beginning of the (uuencoded) binary say simply ``sources are Intel proprietary'': no license or even a copyright notice. If we were able to use this emulator, it would solve all our FP emulation problems (says Rod, who has seen the source); it's very complete. -GAWollman -- Garrett A.
