    Description

      while compiling an GUI application with Msvc2015 32 bit compiler reports error function already defined.

       1>C:\Qt\Qt5.10.0\5.10.0\msvc2015\include\QtCore/qchar.h(94): error C2535: 'QChar::QChar(ushort) noexcept': member function already defined or declared
1> C:\Qt\Qt5.10.0\5.10.0\msvc2015\include\QtCore/qchar.h(82): note: see declaration of 'QChar::QChar'

      Seems to be regression from 5.9 to 5.10.

      Steps to reproduce:
      Modify msvc-desktop.conf mkspec:

      QMAKE_CFLAGS = -nologo -Zc:wchar_t

      to

      QMAKE_CFLAGS = -nologo -Zc:wchar_t-
