msvc 14 test_layout_stride compilation error #304

Hi!

I would like to pack the library (version 0.6.0, not from the master) by build2 (build2.org), but I have the following error (C2039):

I'm not sure is it an error of the library, but I have not find any configuration for msvc in CMakeLists.txt (my script works fine with gcc/clang).
