2433 dnl We also publish the information via G_ATOMIC_LOCK_FREE in case the

2437 dnl We can currently support the atomic ops natively when building GLib
2438 dnl with recent versions of GCC or MSVC. MSVC doesn't run ./configure,
2439 dnl so we skip that case here and define G_ATOMIC_LOCK_FREE exactly when
2440 dnl we are using GCC.
