17.3.3.1.3 External linkage                 [lib.extern.names] 

[ADD THE INDENTED TEXT:]

1 Each name declared as an object with external linkage in a header is reserved 
to the implementation to designate that library object with external 
linkage, 156)

     both in namespace std and in the global namespace.

4 Each name from the Standard C library declared with external 
linkage is reserved to the implementation for use as a name with
extern "C" linkage,

     both in namespace std and in the global namespace.

5 Each function signature from the Standard C library declared with 
external linkage is reserved to the imple­mentation for use as a 
function signature with both extern "C" and extern "C++" linkage,158)

     or as a name of namespace scope in the global namespace.


[ADD A NEW SUBCLAUSE 17.3.3.1.4 AS FOLLOWS:]

-------------------
[Footnote] These types are clock_t, div_t, FILE, fpos_t, lconv, 
ldiv_t, mbstate_t, ptrdiff_t, sig_atomic_t, size_t, time_t, 
tm, va_list, wctrans_t, wctype_t,  and wint_t.
-------------------
the types ::T  and  std::T  are reserved to the implementation and, when defined, 
::T  shall be identical to  std::T .
