The new AC_DEFINE interface deprecates the use of a template file, and instead requires all the information to be provided by the AC_DEFINE commands (it's particularly annoying since the warning about the existence of a template file is about 10 lines long, ALL CAPS, and can't be turned off with --warnings=none).
