Why you were right about leaving the location of the
AC_DECIDE(USE_SYSVSEM_SERIALIZE...) alone?  I had misunderstood the
generated shell script and thought that as soon as one of the
AC_IFALLYES() matched we'd stop executing subsequent tests.  Thus, I
thought that fcntl should be checked for first and SysV sem last in
order to prefer fcntl.  However, the preferred methods have to be
checked for last, so the order has been right all along (well, since
March when you changed it).

That's right, okay, I remember now.  Thanks for the clue.
