One approach to using the atomic builtins would be to have a compile

... and if you search a bit the mailing lists, certainly we discussed a bit the usefulness of adding a builtin macro providing exactly that info. if we cannot change the default i?86 target, that would be definitely very usuful. At some point, I think Richard Guenther even posted a patch essentially complete, then I don't know what happened...
