ARENE_HAS_BUILTIN_ATOMIC

#define ARENE_HAS_BUILTIN_ATOMIC

A platform support query for testing if compiler atomic intrinsics are defined.

Usage:

#if ARENE_IS_ON(ARENE_HAS_BUILTIN_ATOMIC)

The value of this query is determined as follows, in order of precedence:

1. If __atomic_add_fetch, __atomic_fetch_add, etc. intrinsics are available, it is ARENE_ON_BY_DEFAULT
2. Otherwise, it is ARENE_OFF_BY_DEFAULT

ARENE_HAS_BUILTIN_ATOMIC_I_

#define ARENE_HAS_BUILTIN_ATOMIC_I_   ARENE_OFF_BY_DEFAULT
