[Benjamin Kosnik]

Jim,

I see this:

        PR libstdc++/5625
        * libsuspc++/eh_personality.cc (PERSONALITY_FUNCTION): Use
        __builtin_extend_pointer.

And, as per your usual, a very detailed synopsis of this issue here:

http://gcc.gnu.org/ml/gcc-patches/2004-02/msg00606.html

All this appears to be very fine indeed, with one small caveat: there
was no documentation added for this builtin. Any chance you could add
some?
