Cygwin uses whatever is in the newlib tree as of its release date.  That
means that since Cygwin 1.7.7-1 was released in August 2010* it would
incorporate any newlib changes from 2009.  That doesn't mean that we would
export every single thing that newlib provides, however.  If functionality
is missing that means that no one has taken the time to get it working in
the Cygwin DLL.
