Well, there was a test in the past for a specific version of autoconf 
but I believe that was removed.  I see that the default branch 
configure.ac contains AC_PREREQ(2.65) but the most recently checked-in 
version of configure was generated with 2.68.  I understand about the 
desirability of avoiding a lot of churn although it seems to me to not 
be a huge thing; build breaking is another matter, of course.  If we are 
going to mandate a specific version again, that should be documented and 
checked for.
