I'm going to revert again the whole thing and wait for a different, safe, approach, sorry.
In the short time frame, i.e., something solid for 4.4.0, I would suggest two possible strategies:

1- Try to re-organize the new code in order to make possible using in *few* selected places _GLIBCXX_ATOMIC_BUILTINS_4 to enable / disable the new feature completely.

2- Learn from guard.cc. In that libsupc++ implementation file, *certainly* atomic builtins are safely used, with fall-backs.
