Hum, Jerry, I'd really appreciate if you could review my patch at  
http://gcc.gnu.org/ml/gcc-patches/2007-07/msg00911.html, which  
proposes to change this ABI into something more stable for the  
future. Then maybe we could slightly modify yours so that it builds  
on top of mine (this is a rather simple change). If you don't mind  
reviewing my patch (Janne said he would get to it, but was apparently  
bit by real life), I will review yours!
