    Description

      I am trying to build Qt 5.5 Alpha using Visual Studio 2015.
      Here is my config line: .\configure.bat -prefix "E:\Apps\Builds\Qt 5.4.1 MSVC 2015\x64" -debug-and-release -nomake examples -opensource -c++11 -opengl desktop -platform win32-msvc2015 -qt-zlib -qt-pcre -qt-libpng -qt-libjpeg -directwrite -direct2d -mp -no-angle
      However I have some build errors:
      The first one is in iaccessible2.cpp, it's about converting const char16_t [] to const OLECHAR * and I fixed it by adding a reinterpret case like this.

      HRESULT STDMETHODCALLTYPE AccessibleApplication::get_toolkitVersion(/* [retval][out] */ BSTR *version)
      {
          *version = ::SysAllocString(reinterpret_cast<const OLECHAR *>(QT_UNICODE_LITERAL(QT_VERSION_STR)));
          return S_OK;
      }
      

      Second one is much harder to fix and its in `CLucene`:

      Adding the #define mentioned in the first error fixed the hash_map and hash_set error, but the second one is mystery to me. It looks like map can't accept the comparator object.

      I think that the error is somewhere in the IndexReader class in IndexReader.h file. I think this lines is the culprit.

      typedef void (*CloseCallback)(IndexReader*, void*);
      
      class CloseCallbackCompare:public CL_NS(util)::Compare::_base{
      public:
      	bool operator()( CloseCallback t1, CloseCallback t2 ) const{
      		return t1 > t2;
      	}
      	static void doDelete(CloseCallback dummy){
      	}
      };
      
      
      typedef CL_NS(util)::CLSet<CloseCallback, void*, CloseCallbackCompare,
      		CloseCallbackCompare> CloseCallbackMap;
      CloseCallbackMap closeCallbacks;
      

      I have also tried the git version, but the problem isn't solved there.
