The oldest support compiler (with the most bugs) with an buildslave is the cl 14 for ARM. It comes from Visual Studio 2005 for Windwos CE.
It would be great if we can try to keep it compiling with it until a newer version is available. The next version should support all C++11 features available in the desktop version [1] and will be available with Windows Embedded 2013 in Q2 [2].
I already try to keep the impact at an minimum for the trunk, but it's hard if you have a very bad compiler. E.g. the current trunk does not compile [3] due to a compiler bug (some problems with resolving friend classes correctly).
