2426 dnl operations ("lock free") or emulated ones with a mutex. This is
2427 dnl because we must put this information in glibconfig.h so we know if

2431 dnl We also publish the information via G_ATOMIC_LOCK_FREE in case the

2435 dnl We can currently support the atomic ops natively when building GLib
2436 dnl with recent versions of GCC or MSVC. MSVC doesn't run ./configure,
2437 dnl so we skip that case here and define G_ATOMIC_LOCK_FREE exactly when
2438 dnl we are using GCC.
