  12  * __initialize_Cplusplus() is a symbols specific to each shared library that
  13  * can be called in the shared library's initialization routine to force the
  14  * C++ runtime to be initialized so it can be used.  Shared library
  15  * initialization routines are called before C++ static initializers are called
  16  * so if a shared library's initialization routine depends on them it must make
  17  * a call to __initialize_Cplusplus() first.
  18  *
  19  * This function is deprecated in Mac OS X 10.4 because C++ static initializers
  20  * are now called in the correct order.  Therefore, no ppc64 program needs this.
