Build currently fails due to clang being required and not been found:
* Clang (required version >= 3.5) Clang libraries. Used for KDevelop's C++/C support plugin. Please install a package providing libclang.

I don't know the exact setup of the Windows workers, but we could set up LLVM/Clang build via Craft.
Afair the Windows workers are actually bootstrapped using Craft, right?
We use Craft to provide most dependencies yes (apart from Git, Python and Qt).
I've got the builders compiling Clang now, however given that one of the patches doesn't apply (it's building master) I won't be surprised if it fails.
