One of the things you can learn about m4 is that it has no way of
dealing specially with character strings, so if you're using it on
Ada programs and innocently want to do
     Text_IO.Put_Line("This is a UNIX system!");
you could very easily wind up with
     Text_IO.Put_Line("This is a 1 system!");
