There is the 3rd paragraph of the "one definition rule" section:

"Every program shall contain exactly one definition of every non-inline 
function or object that is used in that program; no diagnostic required. The 
definition can appear explicitly in the program, it can be found in the 
standard or a user-defined library, or (when appropriate) it is implicitly 
defined (see 12.1, 12.4 and 12.8). An inline function shall be defined in 
every translation unit in which it is used."

Note they include "user-defined library".
