--- Comment #11 from Thomas Rodgers <rodgertq at gcc dot gnu.org> --- (In reply to Mkkt Bkkt from comment #9) > Why do you think you smarter than msvc stl, libc++, boost::atomic developers? > > Maybe it's about your "I"? I should ignore this (see jwakely's response), but - I very much don't think I am smarter than the person (ogir...@apple.com) who implemented libc++'s implementation.
