Indeed, it doesn't need automake to fail. I used automake when I tested this before. The following configure.ac makes autoconf give an error message: AC_INIT([test],[0]) AC_MSG_WARN([[AC_DC] stinks --Iron Maiden]) AC_MSG_WARN([[AC_DC stinks --Iron Maiden]]) AC_OUTPUT The error is configure.ac:2: error: possibly undefined macro: AC_DC If this token and others are legitimate, please use m4_pattern_allow.

Either that, or autoconf could be changed to make it a warning. I don't see any need for that, though: I think it is okay to be an error.
