This is using CURRENT, cvsup'ed Wednesday.  The same failure occurs with
clang and with gcc.  I note that there have been several changes in the
recent past in the obsolete files list regarding semaphore.h.  I will
try again, blowing away both /usr/src and /usr/obj and see if that has
any effect.  Bisection will have to wait until next week.
