2428 dnl operations ("lock free") or emulated ones with a mutex. This is
2429 dnl because we must put this information in glibconfig.h so we know if
2430 dnl it is safe or not to inline using compiler intrinsics directly from
2433 dnl We also publish the information via G_ATOMIC_LOCK_FREE in case the
2434 dnl user is interested in knowing if they can use the atomic ops across
2437 dnl We can currently support the atomic ops natively when building GLib
2438 dnl with recent versions of GCC or MSVC. MSVC doesn't run ./configure,
2439 dnl so we skip that case here and define G_ATOMIC_LOCK_FREE exactly when
2440 dnl we are using GCC (and not mingw*).
2442 dnl Note that the atomic ops are only available with GCC on x86 when

2444 dnl not available but would be available given the right flags, we want
2445 dnl to abort and advise the user to fix their CFLAGS. It's better to do
2446 dnl that then to silently fall back on emulated atomic ops just because
