I periodically get bitten by bug 34115: a compiler configured without

we reconsider the default for 4.5?
Is anyone still manufacturing x86 CPUs that don't support the atomic
instructions?
Should it just be a question of 'manufacturing'? Or should 'using' be a
criterion for any decision?
Not that I disagree with Jason's suggestion, it is probably the right
choice.
