+/*
+ * An implementation of C11 stdatomic.h directly borrowed from FreeBSD
+ * (original copyright follows), with minor modifications for
+ * portability to other systems. Works for recent Clang (that
+ * implement the feature c_atomic) and GCC 4.7+; includes
+ * compatibility for GCC below 4.7 but I wouldn't recommend it.
+ *
+ * Caveats and limitations:
+ * - Only the ``_Atomic parentheses'' notation is implemented, while
+ *   the ``_Atomic space'' one is not.
+ * - _Atomic types must be typedef'ed, or programs using them will
+ *   not type check correctly (incompatible anonymous structure
+ *   types).
+ * - Non-scalar _Atomic types would require runtime support for
+ *   runtime locking, which, as far as I know, is not currently
+ *   available on any system.
