* LGPLv2.1                                                                                                                                        
                                                                                                                                                  
The library part is distributed under LGPLv2.1 or later. See lgpl-2.1.txt for                                                                     
license details. Refer to the individual file headers for details.                                                                                
                                                                                                                                                  
LGPL-compatible source code can statically use the library header using :                                                                         
                                                                                                                                                  
#define _LGPL_SOURCE
#include <urcu.h>

Dynamic-only linking with the LGPL library is used if _LGPL_SOURCE is not
defined. It permits relinking with newer versions of the library, which is
required by the LGPL license.

See lgpl-relicensing.txt for details.
