Ahh, too bad.  I got the idea from this item in the GCC 3.3 changes:

  * A new type attribute, may_alias, has been added. Accesses to
    objects with types with this attribute are not subjected to
    type-based alias analysis, but are instead assumed to be able to
    alias any other type of objects, just like the char type.
