What platforms are people using for Radiance?

Thanks Mark, Rob G., and Lars. I scanned the benchmark page and found a few SPARCs, too. Sun Studio and Sun WorkShop compilers are mentioned.

So far I have:
Mac (PPC/Intel)
Windows (Intel)
Linux (Intel)
Solaris (SPARC/Intel)

Mark, you mentioned you are using Cygwin; is there anyone using Windows and *not* using Cygwin? Any MS SFU or SUA users?
