QtConcurrent header files include errors

I tried including the following header "#include <QtConcurrent/QtConcurrentRun>". I get the below compiler error message

Error output:
c:\qt\qt5.1.1\5.1.1\msvc2010_opengl\include\qtconcurrent\qtconcurrentrun.h(51) : fatal error C1083: Cannot open include file: 'QtConcurrent/qtconcurrentstoredfunctioncall.h': No such file or directory

I have checked the path, the file is present in the directory.

And When I try and include : #include <QtConcurrent/QtConcurrentRun>

The following is the compile output:

..\..\..\..\..\..\..\Qt\Qt5.1.1\5.1.1\msvc2010_opengl\include\QtCore/qdatetime.h(121) : warning C4003: not enough actual parameters for macro 'min'
..\..\..\..\..\..\..\Qt\Qt5.1.1\5.1.1\msvc2010_opengl\include\QtCore/qdatetime.h(121) : error C2589: '(' : illegal token on right side of '::'
..\..\..\..\..\..\..\Qt\Qt5.1.1\5.1.1\msvc2010_opengl\include\QtCore/qdatetime.h(121) : error C2059: syntax error : '::'

I'm not sure if this is an existing bug or a new one, or if there is a fix for this. Searched in the internet found nothing related to this. Please look into this issue. Thank you
