Sorry, the error message is:

```
configure.ac:2: error: undefined or overquoted macro: AC_MSG_NOTICE
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.
configure.ac:2: error: undefined or overquoted macro: AC_PACKAGE_NAME

```

By the way even with AC_PACKAGE_NAME removed from inside AC_MSG_NOTICE this
error persists.
