HELP! #warning "Inclusion of header files from include/Qt is deprecated."

[yuzhouzhiwai]

hello,
I upgrade my qt from 4.3 to 4.7. And I found many files in the directory "include/Qt/*" increase some code like this:

#ifndef QT_NO_QT_INCLUDE_WARN
    #if defined(__GNUC__)
        #warning "Inclusion of header files from include/Qt is deprecated."
    #elif defined(_MSC_VER)
        #pragma message("WARNING: Inclusion of header files from include/Qt is deprecated.")
    #endif
#endif

#ifndef QT_NO_QT_INCLUDE_WARN
    #if defined(__GNUC__)
        #warning "Inclusion of header files from include/Qt is deprecated."
    #elif defined(_MSC_VER)
        #pragma message("WARNING: Inclusion of header files from include/Qt is deprecated.")
    #endif
#endif

To copy to clipboard, switch view to plain text mode 

That means, if I want to avoid the warning message , I must define the micro "QT_NO_QT_INCLUDE_WARN" ? But what is the meaning of warning message ?

thanks
