2301 dnl operations ("lock free") or emulated ones with a mutex. This is
2302 dnl because we must put this information in glibconfig.h so we know if
2303 dnl it is safe or not to inline using compiler intrinsics directly from
2306 dnl We also publish the information via G_ATOMIC_LOCK_FREE in case the
2307 dnl user is interested in knowing if they can use the atomic ops across
2310 dnl We can currently support the atomic ops natively when building GLib
2311 dnl with recent versions of GCC or MSVC. MSVC doesn't run ./configure,
2312 dnl so we skip that case here and define G_ATOMIC_LOCK_FREE exactly when
2313 dnl we are using GCC.

2317 dnl not available but would be available given the right flags, we want
2318 dnl to abort and advise the user to fix their CFLAGS. It's better to do
2319 dnl that then to silently fall back on emulated atomic ops just because
