Not that I know of. I just think it makes sense to use them if they're available (and work correctly) instead of needing to write our own.

`server/fd.c` defines `atomic_store_*(volatile *ptr, value)` as `*ptr = value` on x86/x86_64. I'm not sure why it defines its own set of atomic helpers, when it also has access to the macros in `include/winnt.h` indirectly.
