------- Comment #14 from jvdelisle at gcc dot gnu dot org 2010-06-01 02:09 ------- My take on this as I was reading through this thread before I got to comment #13 is that the code has to be illegal. I vote for the error. I think it would be bad practice too introduce this as an extension or for some other reason.
