I know this is asking a lot, but could you possibly submit a glibc patch too so the intended value (128 I guess?) is established on their side too, or (yay if you can!) poke somebody else to do it? In the past I've tried to just get them to casually agree to assigning values for things like this before they implement them, but I haven't had much luck. Cc'ing libc-alpha too. Rich
