Well, in C++, abort() is declared in <cstdlib> header, and the standard 
also says this:

"....
 [lib.support.start.term] 18.3 Start and termination

 1 Header <cstdlib> (partial), Table 18:

 2 The contents are the same as the Standard C library header <stdlib.h>, 
   with the following changes:

  abort(void)

 3 The function abort() has additional behavior in this International 
   Standard:                ^^^^^^^^^^^^^^^^^^^

   — The program is terminated without executing destructors for objects 
     of automatic or static storage duration and without calling the 
     functions passed to atexit() (3.6.3).

    extern "C" int atexit(void (* f)(void))
    extern "C++" int atexit(void (* f)(void))
 ...."
