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.
See the Autoconf documentation.

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.
