My only comment is that the likely users of FSF gcc are also likely builders of
ported unix code. So gcc 4.6 needs a big fat warning that existing ported unix
code will have to be vetted for the use of flat-namespace and the linkages
manually adjusted. Otherwise will users of gcc 4.6 will unknowingly miscompile
lots of existing unix code. Since we don't link this way in gcc 4.5, I don't
see why we can't just revert the behavior and postpone this change until gcc
4.7 when it can be more carefully done.
