Removal of support for GCC hosted on UWIN

That's confused, Interix has exactly the same status as Win32, it is a
subsystem of NT. You cannot use the NT kernel directly (for one thing, its
interfaces are not documented -- it is probably the only kernel in the world
which is not only proprietary, but its interfaces are considered proprietary
and secret -- and the Navy declares it to be an "open system" :-)

So in practice using NT means using NT + one of the subsystems, and the
combination of the two corresponds to a normal operating system.

So if it is OK to call Win32 an OS (and people usually mean NT kernel + Win 32
subsystem when they say NT), then it is equally right to call the NT kernel
+ Interix an OS).
