torvald at gcc dot gnu.org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |torvald at gcc dot gnu.org --- Comment #10 from torvald at gcc dot gnu.org --- The difference is unfortunate, but C11 specifies that atomic_is_lock_free is *per object*. I suppose that any change there would have to go through the ISO C process.
