2194 dnl because we must put this information in glibconfig.h so we know if
2195 dnl it is safe or not to inline using compiler intrinsics directly from
2198 dnl We also publish the information via G_ATOMIC_LOCK_FREE in case the

2202 dnl We can currently support the atomic ops natively when building GLib
2203 dnl with recent versions of GCC or MSVC. MSVC doesn't run ./configure,
2204 dnl so we skip that case here and define G_ATOMIC_LOCK_FREE exactly when
2205 dnl we are using GCC (and not mingw*).
2207 dnl Note that the atomic ops are only available with GCC on x86 when

2209 dnl not available but would be available given the right flags, we want

2211 dnl that then to silently fall back on emulated atomic ops just because
