>Description:

gcc should allow to apply the visibility attribute to classes and other complex
types. It should behave as if the visibility attribute was specified on each member
function and variable, unless one of them "overwrites" the setting by specifying a custom
visibility. 

This feature is necessary to easily control the amount of exported symbols in bigger
C/C++ projects. 

>How-To-Repeat:

try to compile this example file: 

#include <stdio.h>

class __attribute__( ( visibility( "hidden" ) ) ) MyClass
{
public:
    MyClass();

    static int member;
};

int MyClass::member;

MyClass::MyClass()
{ }

int main()
{
    MyClass f;
    printf( "%d",MyClass::member );
    return 0;
}

#g++ -Wall test.cc
test.cc:9: warning: `visibility' attribute does not apply to types

 can you please merge this report with c++/9282 ? I've reported it twice 
 because somehow GNATS was broken inbetween. 
 
 Thanks,
