    NPTL doesn't support _POSIX_MESSAGE_PASSING yet, because the
    kernel doesn't support it yet (patches are floating around though
    and as soon as kernel starts supporting NPTL will add support
    for it).

    #include <unistd.h> and check the various _POSIX_* macros
    (or browse /usr/include/{,nptl/}bits/posix_opt.h) or use sysconf/getconf
    (for mq_* sysconf (_SC_MESSAGE_PASSING) or getconf MESSAGE_PASSING). See
    for details.
