XFree 1.2 was compiled Assuming this is a correct description of the original poster's system, he IMHO will be MUCH better off if he runs out and gets a coprocessor. Personally, I recommend Cyrix. The emulator in 386BSD consumes a lot of overhead and is quite slow. For example (on my 386SX/16, without a coprocessor, whetstone (FP benchmark) took over 8 minutes of wall clock time to run. Ghostscript (another relatively high FP-using program) would take 20 minutes just to initialize. With a coprocessor installed, the run time went to a second or two. >results or will crash.

The good news is that Which will most likely make such applications quite slow if no coprocessor is found. And, gcc 1.39 isn't exactly bug-free or optimal in its code generation either. I would recommend that gcc-2.3.3 still be used to compile Xfree, and somewhere in the relevant FAQs state that X requires a coprocessor. >-sl >>-- -- David E.
