dnl NOTE: Automake < 1.12 didn't have serial-tests and gives an error if it

dnl sees this, but for automake >= 1.13 serial-tests is required so we have to

dnl include it.  Solution is to test for the version of automake (by running

dnl an external command) and provide it if necessary.  Note we have to do this

dnl entirely using m4 macros since automake queries this macro by running

dnl 'autoconf --trace ...'.
