You might be formally right, but what about practical consequences? Unless  
*all* libraries I use have push/pops in *every single header*, using  
-fvisibility for my own library can result in crash. So for a large 
application you'd need to get authors of all used libraries to "fix" them! 
Note that even libstdc++ does not have this at the moment. This makes 
-fvisibility just useless.
