2334 dnl operations ("lock free") or emulated ones with a mutex. This is
2335 dnl because we must put this information in glibconfig.h so we know if

2339 dnl We also publish the information via G_ATOMIC_LOCK_FREE in case the
2340 dnl user is interested in knowing if they can use the atomic ops across
2343 dnl We can currently support the atomic ops natively when building GLib
2344 dnl with recent versions of GCC or MSVC. MSVC doesn't run ./configure,
2345 dnl so we skip that case here and define G_ATOMIC_LOCK_FREE exactly when
2346 dnl we are using GCC.

2350 dnl not available but would be available given the right flags, we want
2351 dnl to abort and advise the user to fix their CFLAGS. It's better to do
