Hmm, I'm not comfortable with deliberately regressing this testcase.

  template <typename T>
-void bar (void (T[5])); // { dg-error "array of 'void'" }
+void bar (void (T[5])); // { dg-error "array of 'void'" "" { xfail
*-*-* } }

Can we work it so that T[5] also is un-decayed in the DECL_ARGUMENTS of 
bar, but decayed in the TYPE_ARG_TYPES?
