2313 dnl because we must put this information in glibconfig.h so we know if
2314 dnl it is safe or not to inline using compiler intrinsics directly from
2317 dnl We also publish the information via G_ATOMIC_LOCK_FREE in case the

2321 dnl We can currently support the atomic ops natively when building GLib
2322 dnl with recent versions of GCC or MSVC. MSVC doesn't run ./configure,
2323 dnl so we skip that case here and define G_ATOMIC_LOCK_FREE exactly when
2324 dnl we are using GCC (and not mingw*).
