Unfortunately, the committed fix does not work, because this is a cmake project, and cmake does not respect LIBS environment variable, which is what is used to implement append-atomic-flags.
Haven't looked too closely but last time I quickly checked mimalloc for atomic issues, it had some cmake logic for this already. It's *probably* just failing to use it when it should here. (that was in a rust crate rather than system's mimalloc, and in the end it no longer use mimalloc so don't think anyone went further with resolving that) Either way the append-atomic can be reverted.
