    libstdc++: Add missing 'inline' to always_inline function
    
    This fixes a -Wattributes warning for the COW std::string which was
    previously suppressed due to being in a system header.
    
    libstdc++-v3/ChangeLog:
    
            * include/bits/cow_string.h (__resize_for_overwrite): Add
            inline keyword to function with always_inline attribute.
