Created an attachment (id=12853)

A test case
When I compile the attached test case, I get:
[EMAIL PROTECTED] test-cases]$ make
g++ -W -Wall -g hidden.cpp -o hidden
hidden.cpp:5: warning: 'visibility' attribute ignored on non-class types
Line 5 refers to the declaration with the attribute attached to the return
type.
Looking at the generated ELF file, I see that "func" is not hidden, but "func2"
is:
[EMAIL PROTECTED] test-cases]$ readelf -s hidden | c++filt | grep func
51: 080487f2 23 FUNC LOCAL DEFAULT 12 global constructors keyed to
_Z4funcv
53: 08049e80 4 OBJECT LOCAL DEFAULT 25 func2()::foo2
55: 08049e90 4 OBJECT LOCAL DEFAULT 25 func()::foo
59: 08049e78 8 OBJECT LOCAL DEFAULT 25 guard variable for
func2()::foo2
60: 08049e88 8 OBJECT LOCAL DEFAULT 25 guard variable for
func()::foo
89: 080488fa 220 FUNC GLOBAL DEFAULT 12 func()
99: 0804881e 220 FUNC GLOBAL HIDDEN 12 func2()
