Indeed, ubuntu's autom4te (current version 2.64-1ubuntu1) turns out to 
be different from the original 2.64. In ubuntu's version, line 1038 is 
the following:

 msg $cat, $loc, "warning: $msg";


Here is the diff between the original autom4te and the ubuntu version:

I don't know if this is useful, but here is the Changelog for Ubuntu's 
autoconf package:
