2314 dnl operations ("lock free") or emulated ones with a mutex. This is
2315 dnl because we must put this information in glibconfig.h so we know if
2316 dnl it is safe or not to inline using compiler intrinsics directly from
2319 dnl We also publish the information via G_ATOMIC_LOCK_FREE in case the
2320 dnl user is interested in knowing if they can use the atomic ops across
2323 dnl We can currently support the atomic ops natively when building GLib
2324 dnl with recent versions of GCC or MSVC. MSVC doesn't run ./configure,
2325 dnl so we skip that case here and define G_ATOMIC_LOCK_FREE exactly when
2326 dnl we are using GCC.

2330 dnl not available but would be available given the right flags, we want
2331 dnl to abort and advise the user to fix their CFLAGS. It's better to do
2332 dnl that then to silently fall back on emulated atomic ops just because
