    PR libobjc/50428
    * sendmsg.c (__objc_send_initialize): If a class does not have an
    +initialize method, search for an +initialize method in the
    superclass and in the ancestor classes and execute the first one
    that is found.  This makes the GNU runtime behave in the same way
    as the Apple/NeXT runtime with respect to +initialize methods and
    subclassing.

    * doc/objc.texi (Garbage Collection): Updated example to protect
    +initialize against execution in subclasses.
