+dnl 2.13 definitely chokes; 2.53 is the earliest version I've tested.
+dnl 2.58 needed for help string macro but that only affects help output
dnl 2.50 is the major breakpoint between the old autoconf and the new,
dnl so require that. If there are bug reports about 2.50-2.52 not working
dnl we can always move this up a little.
