2336 dnl We also publish the information via G_ATOMIC_LOCK_FREE in case the

2340 dnl We can currently support the atomic ops natively when building GLib
2341 dnl with recent versions of GCC or MSVC. MSVC doesn't run ./configure,
2342 dnl so we skip that case here and define G_ATOMIC_LOCK_FREE exactly when
2343 dnl we are using GCC.

2348 dnl to abort and advise the user to fix their CFLAGS. It's better to do
