As I understand, the most recent arache versions (https://www.glennmcc.org/arachne/) are provided either optimised for a 387 system, or general purpose one for the 8086. I have a 286 system with an FPU and am curious to see if there would be much of a performance difference using the FPU and maybe taking advantage of a few of the instructions available on the 286 but not 8086. The sourcecode is available but I don't see a clear way to compile it for 287 and I was wondering if anybody has experience with doing this in the past or may know of how to do it. I can understand a certain amount of code, but don't really know stuff like the structure of large multi-file codebases, so I am a bit confused by Arachne's code.
