Would love to. Someone playing with same compile tried -o6!
However, as I posted, -o3 would compile with G++4.0 but not with G++4.1, thus 
this bug.

(Meanwhile, am I better off with the -o3 4.0 compile or with the -o2 4.1 
compile? )

BTW, others reported various but related problems with 64-bit compiles. 
Reported on Linux Audio User's List linux-audio-user@lists.linuxaudio.org. I 
would assume their site has an archive where the whole thread could be 
viewed. I will forward this response to this list as well.
