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
(Meanwhile, am I better off with the -o3 4.0 compile or with the -o2 4.1
BTW, others reported various but related problems with 64-bit compiles.
Reported on Linux Audio User's List email@example.com. 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.
