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`:

C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\INCLUDE\hash_map(17): error C2338: <hash_map> is deprecated and will be REMOVED. Please use <unordered_map>. You can define _SILENCE_STDEXT_HASH_DEPRECATION_WARNINGS to acknowledge that you have received this warning.

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.
