Currently, if someone runs bootstrap.sh (not required for releases or instant releases) and has Autoconf 2.59 installed, it works fine (as long as the environment is sane), but generates some scary and potentially confusing error messages. We could update the AC_PREREQ to 2.61, which would change the scary and confusing non-fatal errors into a very clear, but fatal, error.
Do you guys think this would be an improvement? --David
