Very good

Ah okay I thought (probably had to read better) something goes wrong if
you remove when you should not.  Then is even easier yes!

If you diff the full branch I had to adjust few thing in Emacs too to
have it working, I believe is expected.  You'll check for the presence
of the native compiler in Lisp with the function you've introduced in
one of your patches.

I believe also that the renaming mechanism should be transparent on all
posix where is not necessary.
