It would have been preferable to have posted a reminder mail about
them requiring a review than just committing them.  Are these
changes necessary for the 14.01 branch?  I ask, because I had almost
finished testing the current 14.01.1-beta on Windows (in all the various
combination of build environment / C compilers) and this means I will
have to do so all over again.

Cheers,
Julien.
