> If we wanted to do this for Wine, then it would also require emulation or something like OS X's Hypervisor.framework to catch system calls, which seems heavyhanded when we have working code already. It could also be done as a kernel level loadable module in the sort of style this Linux subsystem is being done, which is more what I was thinking. Changing a few numbers for every Windows service pack (really, not even necessary if you only support certain versions of ntdll for example) might not be so bad compare to re-implementing bug level compatibility with every Windows API. Calling Wine "working" in its current state is a bit of an overstatement.
