These compile options are highly recommended. The mmx/sse things are 
there because the linux 1.5 jvm has a bug where it doesn't properly 
align the C stack to 16 bytes which causes mmx instructions to crash, 
hence we need to disable it when running java apps.

If you use a 64-bit linux distro with the 64-bit virtual machine from 
Sun, it should work. That comment is no longer valid.

You will always have to to build qt and jambi from source when doing 
bindings to be sure of binary compatibility.
