> I doubt much will be merged upstream. Many updates we have can technically run on other OSes (%gs stubs won't be built on Linux because %gs is correctly set, SIGUSR1 will work but less optimally, etc). However I picked an approach where everything that is done for OpenBSD is just marked as OpenBSD only. I did that purely to simplify my life while I was working on it and clearly mark the changes.

> When I was talking to Wine maintainers a month ago, they were hesitant to accept even patching Wine so it compiles for OpenBSD, mostly because it's another OS they will have to support and keep operational, while the %gs stub fix is something they definitely cannot take upstream. They are very hesitant to take anything that is changing the "emulated" application code.
