2429 dnl We also publish the information via G_ATOMIC_LOCK_FREE in case the

2433 dnl We can currently support the atomic ops natively when building GLib
2434 dnl with recent versions of GCC or MSVC. MSVC doesn't run ./configure,
2435 dnl so we skip that case here and define G_ATOMIC_LOCK_FREE exactly when
2436 dnl we are using GCC.
