Wine should still load its builtin libs first. Your going to need to
add some configure magic to detect interix/SFU and get it building.
The last time I tried I ran in to conflicts with headers. It seems
what Microsoft has for basic types in the POSIX headers does not match
what windows has.

You can already test any of the pure Win32 Wine dlls if you do a mingw
build. Trying to to a port is a good bit of work.

A port to SFU has the same problems as a Cygwin port. Your going to
have to implement support in ntdll and wineserver for
get/setthreadcontext. For simple Win32 apps that can just be stubbed
but then you have the harder task of implementing or working around
the lack of send/recvmsg. I think there was a hack to emulate it for
cygwin but I never got around to testing it so you might be able to
come up with a creative solution that will work for both targets. My
advice would be to get it working on cygwin first and then port to
