2305 dnl because we must put this information in glibconfig.h so we know if
2306 dnl it is safe or not to inline using compiler intrinsics directly from
2309 dnl We also publish the information via G_ATOMIC_LOCK_FREE in case the
2310 dnl user is interested in knowing if they can use the atomic ops across
2313 dnl We can currently support the atomic ops natively when building GLib
2314 dnl with recent versions of GCC or MSVC. MSVC doesn't run ./configure,
2315 dnl so we skip that case here and define G_ATOMIC_LOCK_FREE exactly when
2316 dnl we are using GCC (and not mingw*).
