--- Comment #22 from Jack Howarth <howarth at nitro dot med.uc.edu> 2011-02-01 16:57:04 UTC --- 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.
