That's the default, so it should make no difference.

That should be fine.  But update to today's CVS with no extra patches
just to be sure.

If it's still doing this, then I would recommend a debugging printf in
linux-low.c, right before the new if statement with the pass_signals[]
check.  pass_signals[target_signal_from_host (WSTOPSIG (wstat))] ought
to be set for SIGALRM, and we ought not to return it to GDB, but your
log says we did that.
