The latest C1X draft mentions a macro called ATOMIC_VAR_INIT() that can be used
to initialize an atomic variable.

_Atomic(int) i = ATOMIC_VAR_INIT(3);

As an experiment, I implemented a C-centric version of <stdatomic.h> for


Now the question is: how should I implement ATOMIC_VAR_INIT()? It seems like
assigning values to these variables directly doesn't work:

error: initializing '_Atomic(int)' with an expression of incompatible type
_Atomic(int) x = 3;
