Confirmed. Section 16.8/1 states: 
--------------------------------- 
  16.8  Predefined macro names                          [cpp.predefined] 
 
1 The following macro names shall be defined by the implementation: 
 
  __LINE__ 
      The line number of the current source line (a decimal constant). 
  [...] 
--------------------------------- 
However, later on we read (in subclause 3): 
--------------------------------- 
3 If any of the pre-defined  macro  names  in  this  subclause,  or  the 
  identifier   defined,  is  the  subject  of  a  #define  or  a  #undef 
  preprocessing directive, the behavior is undefined. 
--------------------------------- 
 
In other words, what you want doesn't work.
