2442 dnl because we must put this information in glibconfig.h so we know if
2443 dnl it is safe or not to inline using compiler intrinsics directly from
2446 dnl We also publish the information via G_ATOMIC_LOCK_FREE in case the
2447 dnl user is interested in knowing if they can use the atomic ops across
2450 dnl We can currently support the atomic ops natively when building GLib
2451 dnl with recent versions of GCC or MSVC. MSVC doesn't run ./configure,
2452 dnl so we skip that case here and define G_ATOMIC_LOCK_FREE exactly when
2453 dnl we are using GCC (and not mingw*).

2458 dnl to abort and advise the user to fix their CFLAGS. It's better to do
2459 dnl that then to silently fall back on emulated atomic ops just because
