2303 dnl because we must put this information in glibconfig.h so we know if
2304 dnl it is safe or not to inline using compiler intrinsics directly from
2307 dnl We also publish the information via G_ATOMIC_LOCK_FREE in case the
2308 dnl user is interested in knowing if they can use the atomic ops across
2311 dnl We can currently support the atomic ops natively when building GLib
2312 dnl with recent versions of GCC or MSVC. MSVC doesn't run ./configure,
2313 dnl so we skip that case here and define G_ATOMIC_LOCK_FREE exactly when
2314 dnl we are using GCC (and not mingw*).
2316 dnl Note that the atomic ops are only available with GCC on x86 when

2318 dnl not available but would be available given the right flags, we want
2319 dnl to abort and advise the user to fix their CFLAGS. It's better to do
2320 dnl that then to silently fall back on emulated atomic ops just because
