      Failed to build application that uses QDateTime class with Visual C++ 11.0 due to absence of macro NOMINMAX (Windows specific):

      1>d:\users\marat\documents\work\cpp\qt_5_0_2_msvc2012_shared\qtbase\include\qtcore\../../src/corelib/tools/qdatetime.h(123): warning C4003: not enough actual parameters for macro 'min'
1>d:\users\marat\documents\work\cpp\qt_5_0_2_msvc2012_shared\qtbase\include\qtcore\../../src/corelib/tools/qdatetime.h(123): error C2589: '(' : illegal token on right side of '::'

      If Qt needs NOMINMAX to be defined for building itself - that's ok. But I think that Qt shouldn't require this macro definition from users of Qt. Solution is very simple - make public headers of Qt independent of NOMINMAX (see qdatetime.h.patch).
