2439 dnl We need to decide at configure time if GLib will use real atomic
2440 dnl operations ("lock free") or emulated ones with a mutex. This is
2441 dnl because we must put this information in glibconfig.h so we know if
2442 dnl it is safe or not to inline using compiler intrinsics directly from
2445 dnl We also publish the information via G_ATOMIC_LOCK_FREE in case the
2446 dnl user is interested in knowing if they can use the atomic ops across
2449 dnl We can currently support the atomic ops natively when building GLib
2450 dnl with recent versions of GCC or MSVC. MSVC doesn't run ./configure,
2451 dnl so we skip that case here and define G_ATOMIC_LOCK_FREE exactly when
2452 dnl we are using GCC (and not mingw*).
2454 dnl Note that the atomic ops are only available with GCC on x86 when

2456 dnl not available but would be available given the right flags, we want
2457 dnl to abort and advise the user to fix their CFLAGS. It's better to do
2458 dnl that then to silently fall back on emulated atomic ops just because
