Windows x64 ruby build, or VC2005?

What is the status of ruby compiling for x64 on MSVC 2005?
For that matter, what is the status of ruby compiling 32-bit on MSVC
2005?
Should I spend some effort doing that (the 32-bit at least) or would I
be wasting my time?

Apologies for my question about compiling on VC2005. I see it compiles
just fine.
My question about x64 on Windows remains though.
