See below: Changing "1" and "2" to "m" made the warnings disappear. But
you say that this is not the correct solution. Care to explain what that
code is doing and what the changes mean?
File: sysdeps/mach/hurd/i386/intr_msg.h.
/* Note that we must mark OPTION and TIMEOUT as outputs of this
operation, to indicate that the signal thread might mutate them as part
of sending us to a signal handler. */

timeout, notify) \
