is that "Qt mkspec" also working with Qbs?

so i think it would be better using Qt5.8 for the first tests and try to 
get back to 5.6 later

what about the C compiler detection problems?

(as i wrote) i've installed the current svn version of clang-cl from the 
LLVM homepage
and my QtCreator 4.4.1 detected this C++ compiler:

LLVM 64bit based on MSVC2015 | Clang
Initalization: ...\vcvarsall.bat amd64
LLVM: C:\Program Files\LLVM

but no C compiler

should i upgrade to QtCreator 4.5 or later, or is the missing C compiler
handler by the “win32-clang-msvc” spec?
