I mean just what I said: rt_tgsigqueueinfo's treatment of the siginfo_t
should match rt_sigqueueinfo's.  Make it match rt_sigqueueinfo today and
make sure that if rt_sigqueueinfo changes, then rt_tgsigqueueinfo will
change to match.

I don't see any problem.  But you should at least make sure that Ulrich
likes the syscall interface for implementing pthread_sigqueue or whatever
it will be.
