+dnl Initialize automake.  automake < 1.12 didn't have serial-tests and
+dnl gives an error if it sees this, but for automake >= 1.13
+dnl serial-tests is required so we have to include it.  Solution is to
+dnl test for the version of automake (by running an external command)
+dnl and provide it if necessary.  Note we have to do this entirely using
+dnl m4 macros since automake queries this macro by running
+dnl 'autoconf --trace ...'.
