Porting any POSIX/ELF OS should be very simple.

- add OS detection to makefiles
- add in OS specific struct layouts in core.sys (ucontext_t, siginfo_t,  
sockaddr...)
- add rt.memory functions, using the linker script to find static segment  
brackets


We use the following pattern all over the place.

version (Windows) {}
else version (OSX) {}
else version (linux) {}
else version (FreeBSD) {}
else static assert(0);

For anything but struct layouts the following would be correct.

version (Windows) {}
else version (linux, OSX) {} // iff specialized
else version (POSIX) {}
else static assert(0);

Because of this you'll need to change core.{thread...} and dmd as well.

I'm not stepping into the discussion below but I don't see the point of
differencing FreeBSD, NetBSD, OpenBSD, DragonFlyBSD, Darwin, Solaris,  
OpenIndiana...
After all that's what POSIX was made for.

Have a look at core.sync.mutex which will work on all of these platforms.
