2316 dnl because we must put this information in glibconfig.h so we know if
2317 dnl it is safe or not to inline using compiler intrinsics directly from
2320 dnl We also publish the information via G_ATOMIC_LOCK_FREE in case the
2321 dnl user is interested in knowing if they can use the atomic ops across
2324 dnl We can currently support the atomic ops natively when building GLib
2325 dnl with recent versions of GCC or MSVC. MSVC doesn't run ./configure,
2326 dnl so we skip that case here and define G_ATOMIC_LOCK_FREE exactly when
2327 dnl we are using GCC (and not mingw*).

2332 dnl to abort and advise the user to fix their CFLAGS. It's better to do
2333 dnl that then to silently fall back on emulated atomic ops just because
