It may be useful to limit the variety of autoconfs in use by setting AC_PREREQ 
to, say, 2.68.
Eeek! 2.61! I believe our current minimum is 2.67 (though 2.68 seems common and 
reasonable)
Yeah - 
http://hg.openjdk.java.net/jdk8/jdk8/file/056398db9dcb/common/autoconf/configure.ac
says        33 AC_PREREQ([2.61])
so bumping it to 2.68 (or at least 2.67) may be reasonable.

I just checked around on the various systems I'm usually building on. 2.67 is default on my very old Ubuntu. The new Ubuntu I'm switching to has 2.69. On cygwin you get 2.69, on Solaris I used OpenCSW which also provided 2.69. On mac I have only managed to get autoconf through building a source bundle anyway.

In summary, 2.69 seems readily available on modern OSes and isn't hard to install if it isn't. I think we should change the macro AC_PREREQ to 2.69.
