2355 dnl We can currently support the atomic ops natively when building GLib
2356 dnl with recent versions of GCC or MSVC. MSVC doesn't run ./configure,
2357 dnl so we skip that case here and define G_ATOMIC_LOCK_FREE exactly when
2358 dnl we are using GCC.

2363 dnl to abort and advise the user to fix their CFLAGS. It's better to do
