Until we're ready to distribute the kernel, there doesn't seem to be much point in distributing the compiler. Note though that the amd64 port currently does not permit the use of 64-bit addressing in user processes nor I/O above 4GB, though that's not really an issue, since it all goes through the kernel. I believe Jim said that the amd64 kernel can exploit physical memory beyond 4GB. Having said all that, I believe Vitanuova are doing the compiler work, so they may have other opinions about availability.
