No, it doesn't.  It will still do whatever the
compiler does by default, which is the right
thing to do anyway.  The change was to make these
properties available for libraries that need
to select different implementations based on
these properties. i.e. choosing x86_64 asm vs
i686 asm in Boost.Context.
