2298 dnl because we must put this information in glibconfig.h so we know if
2299 dnl it is safe or not to inline using compiler intrinsics directly from
2302 dnl We also publish the information via G_ATOMIC_LOCK_FREE in case the

2306 dnl We can currently support the atomic ops natively when building GLib
2307 dnl with recent versions of GCC or MSVC. MSVC doesn't run ./configure,
