+dnl We need to decide at configure time if GLib will use real atomic
+dnl operations ("lock free") or emulated ones with a mutex. This is
+dnl because we must put this information in glibconfig.h so we know if
+dnl it is safe or not to inline using compiler intrinsics directly from
+dnl the header.
+dnl
+dnl We also publish the information via G_ATOMIC_LOCK_FREE in case the
+dnl user is interested in knowing if they can use the atomic ops across
+dnl processes.
+dnl
+dnl We can currently support the atomic ops natively when building GLib
+dnl with recent versions of GCC or MSVC. MSVC doesn't run ./configure,
+dnl so we skip that case here and define G_ATOMIC_LOCK_FREE exactly when
+dnl we are using GCC (and not mingw*).
+dnl
+dnl Note that the atomic ops are only available with GCC on x86 when
+dnl using -march=i486 or higher. If we detect that the atomic ops are
+dnl not available but would be available given the right flags, we want
+dnl to abort and advise the user to fix their CFLAGS. It's better to do
+dnl that then to silently fall back on emulated atomic ops just because
+dnl the user had the wrong build environment.
+
+dnl We may add other compilers here in the future...
