 // PR c++/10091
 
+// Original synopsis
 // Bug: We were dying because in general, B::a doesn't have enough
 // alignment for us to take its address.  But if the B is C::b, it does
 // have enough alignment, and we should be able to determine that.
 
 // This only failed on STRICT_ALIGNMENT targets (i.e. not i686)
 
+// July 2003
+// packing of non-pods is now only allowed if the non-pod is itself
+// packed. Also only such pods can be reference bound to non-consts
