Successfully tested on Linux. It emits less warnings than GCC, I will focus on fixing these ones first.

Thanks for sharing that result...

Update: it worked on an amd64 box, but fails now on x86

Linking CXX shared library Unix/i686-Release-32/libTKService.so

Systems are quite different, so this may not be due to different architectures.

This is a clang bug on x86, see
http://llvm.org/bugs/show_bug.cgi?id=10022

Fortunately there is a trivial workaround, fix committed at b710256. I am closing this issue, please file a new one if there are problems with clang support.
Thanks for your suggestion.

Amazing work Denis, wonderful to see this realized so lightning fast!
