2324 dnl because we must put this information in glibconfig.h so we know if
2325 dnl it is safe or not to inline using compiler intrinsics directly from
2328 dnl We also publish the information via G_ATOMIC_LOCK_FREE in case the
2329 dnl user is interested in knowing if they can use the atomic ops across
2332 dnl We can currently support the atomic ops natively when building GLib
2333 dnl with recent versions of GCC or MSVC. MSVC doesn't run ./configure,
2334 dnl so we skip that case here and define G_ATOMIC_LOCK_FREE exactly when
2335 dnl we are using GCC (and not mingw*).
