I think it is due to the modifications of syscall.h I made to implement
pseudo-signals handling, which implementation was never finished, and
removed in xenomai-head. Could you try xenomai-head to see if you get
the failure? I tried backporting it, but the code evolved too much in
both repositories, the backport needs to spend some time on it, so, I
would like to know whether it is really needed.
