2336 dnl operations ("lock free") or emulated ones with a mutex. This is
2337 dnl because we must put this information in glibconfig.h so we know if

2341 dnl We also publish the information via G_ATOMIC_LOCK_FREE in case the
2342 dnl user is interested in knowing if they can use the atomic ops across
2345 dnl We can currently support the atomic ops natively when building GLib
2346 dnl with recent versions of GCC or MSVC. MSVC doesn't run ./configure,
2347 dnl so we skip that case here and define G_ATOMIC_LOCK_FREE exactly when
2348 dnl we are using GCC.

2353 dnl to abort and advise the user to fix their CFLAGS. It's better to do
