I'm using CodeTyphon for cross-plattform development because it's easy to download, install or even create new crossbuild-toolchains withouth having to tinker with a terminal. Right now I've set it up on a 64-Bit Linux (Mint) and it allows me to compile to Linux 32, Linux 64, Windows 32 and Windows 64. For (the near) future I also plan on setting up cross compile to Mac OSX, so all the platforms I want to support can be compiled from a single development environment.

So if you do cross-platform stuff, I'd go for code typhon. The installation is pretty easy and adding new toolchains with ease is a real plus.
