========== Rebuild All: 0 succeeded, 1 failed, 0 skipped ==========

Up till now I was using a hacked boost-1.62. So in order to see what would
happen, I also built boost-1.63. Apart from a small change in
type_with_alignment.hpp (adding a ckeck for _MSC_VER not to exist if
__clang__ does exist in line 87), boost-1.63 compiles without a problem (no
specific (relevant to the emulation) command line parameters).

Is there a macro I should define or is there something else I should set/do
in order to use boost-1.64 with Clang 4.0.0 on windows? Any other
suggestions?
