Thanks. We do see this happening for members as well such as  
std::vector<T>::_M_insert_aux. Do I understand you correctly the  
option only applies to non-template inline member functions? That  
would be unfortunate as we have by far more template-generated inline  
goo than other origins :-/

Is there any way to override the above restriction to apply to all  
inlines - or at least templates and out-of-class free functions  
included - and/or would a patch to enable such behaviour be accepted?  
Should one expect any major drawbacks for such a change on pretty bog  
standard C++ use, such as standard library or boost?

Is different visibility for template specialisations common for those  
that use the option? I couldn't think of any construct in our code  
that would call for it, and was wondering if there were examples of  
how it's used elsewhere so that I don't misunderstand this feature.
