@hippy dave: What's your host system? (If it's not Linux, you're probably in for a painful experience. Investing in a Linux box/vm may be the fastest/easiest way to get something running).
If on Linux, what everyone said, or use a CodeSourcery prebuilt TC, or build one yourself using your favorite TC-building tool (we're mostly using crosstool-ng & buildroot, FWIW).
We've been over this a few times in here, but we each have our own preferred 'mix'
. Being a Gentoo guy, I'm using a self-built (via ct-ng) slightly
bleeding edge TC.
