2314 dnl because we must put this information in glibconfig.h so we know if
2315 dnl it is safe or not to inline using compiler intrinsics directly from
2318 dnl We also publish the information via G_ATOMIC_LOCK_FREE in case the
2319 dnl user is interested in knowing if they can use the atomic ops across
2322 dnl We can currently support the atomic ops natively when building GLib
2323 dnl with recent versions of GCC or MSVC. MSVC doesn't run ./configure,
2324 dnl so we skip that case here and define G_ATOMIC_LOCK_FREE exactly when
2325 dnl we are using GCC (and not mingw*).
