Actually, Microsoft hasn't.  The Posix subsystem never did anything
useful and was just a cynical hack to satisfy government checklists.
Must support Posix -- check.  But most limits were set as low as they
could go.  OpenNT/Interix/WSU was a third-party product, and was an
entirely separate implementation of Posix, not quite matching any existing
OS.  I ported a large proprietary Linux C++ program to it as a proof
of concept, and there were a lot of issues but it did eventually work.
The intention here is to match the Linux kernel, at least up to a point
(and nobody knows what that point is).

It definitely doesn't affect Cygwin in any way.
