Currently, atomics are an all-or-nothing choice (via __SDTC_NO_ATOMICS__).
I'd like to see a third option: support atomics, except for the creation
of atomic_flag from allocated storage (or raw character arrays). This
would make it feasible to implement atomics for some low-end systems,
that otherwise can't support them efficiently.
Your opinions on the proposal and the proposed wording are welcome: http://www.colecovision.eu/stuff/proposal-atomic_flag.html
