[R] R on AMD64 (Opteron)

[Prof Brian Ripley]

We are using Fedora Core 2 and some version(s) of SuSe Linux on various
dual Opteron servers.  We also have a copy of RHEL, but AFAIK are not
currently using it.  I've been using a dual Opteron 248 under FC2

I don't know that Windows XP 64-Bit Edition is actually released yet 
(although there have beem public betas).  However, as Peter D says, one 
would need a suitable compiler, binutils etc and the MinGW project is 
unlikely to provide them any time soon (if ever, although the project's 
FAQ suggests that it does intend to).
