--- Comment #7 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
"String literals, and compound literals with const-qualified types, need 
not designate distinct objects.".  (This is different from named 
variables, which can't be merged without -fmerge-all-constants unless it 
can be shown there are no address comparisons that would allow the merging 
to be detected.)
