Hi 9fans, I also attempted to build amd64 version some time ago, and it failed in libc. I gave up then, but since someone brought this up, let me ask my question here. Bell Labs doesn't distribute amd64 binaries.

Looks like the labs version does not have amd64 code for libc. Is that correct? And is libc the only missing part? -- Zbigniew Radosz
