Hi,

I guess I would argue that since apps running in the SFU environment (or
more precisely the Interix subsystem component of it) use the POSIX system
API directly, they are as 'native' as anything else running under Windows.
The WIN32 and POSIX system interfaces built in to NT operate at the same
level, so there is no emulation involved. In fact, you can't mix WIN32 and
POSIX calls in the same process - you really are operating completely
independently of what we normally think of as being 'Windows'.

I think in terms of application interoperability within the Windows
environment, you are probably better off using an 'emulation' layer on top
of the WIN32 API such as Cygwin provides, however I suspect there is a
slight performance penalty here. If you're looking for a 'pure' UNIX-like
environment, then SFU is a viable alternative, particularly (as was pointed
out) because its officially supported by MS. It is surprisingly
fully-featured, too - threads, dynamic linking/loading etc.
