2247 dnl operations ("lock free") or emulated ones with a mutex. This is
2248 dnl because we must put this information in glibconfig.h so we know if
2249 dnl it is safe or not to inline using compiler intrinsics directly from
2252 dnl We also publish the information via G_ATOMIC_LOCK_FREE in case the
2253 dnl user is interested in knowing if they can use the atomic ops across
2256 dnl We can currently support the atomic ops natively when building GLib
2257 dnl with recent versions of GCC or MSVC. MSVC doesn't run ./configure,
2258 dnl so we skip that case here and define G_ATOMIC_LOCK_FREE exactly when
2259 dnl we are using GCC (and not mingw*).

2263 dnl not available but would be available given the right flags, we want
2264 dnl to abort and advise the user to fix their CFLAGS. It's better to do
2265 dnl that then to silently fall back on emulated atomic ops just because
