/*
 * 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.
