Compiler error from clang_64 on MacOS

Following two errors wih solution:

1. First
   File:
   /Volumes/data/Qt5.9.2/5.9.2/clang_64/lib/QtCore.framework/Versions/5/Headers/qdebug.h

Code:
141  #ifdef Q_COMPILER_UNICODE_STRINGS
142    inline QDebug &operator<<(char16_t t) { return *this << QChar(ushort(t)); }
143    inline QDebug &operator<<(char32_t t) { putUcs4(t); return maybeSpace(); }
144  #endif

Compiler error:
/Volumes/data/Qt5.9.2/5.9.2/clang_64/lib/QtCore.framework/Headers/qdebug.h:142: Fehler: expected '(' for function-style cast or type construction
    inline QDebug &operator<<(char16_t t) { return *this << QChar(ushort(t)); }
                                                                  ^~~~~~

Solution, change line 142 as followed:
142 inline QDebug &operator<<(char16_t t) { return *this << QChar((ushort)(t)); }

1. Second
   File:
   /Volumes/data/Qt5.9.2/5.9.2/clang_64/lib/QtGui.framework/Versions/5/Headers/qrgba64.h

Code:
123  Q_DECL_CONSTEXPR ushort toRgb16() const
124  {
125      return ushort((red() & 0xf800) | ((green() >> 10) << 5) | (blue() >> 11));
126  }

Compiler error:
/Volumes/data/Qt5.9.2/5.9.2/clang_64/lib/QtGui.framework/Headers/qrgba64.h:125: Fehler: expected '(' for function-style cast or type construction
        return ushort((red() & 0xf800) | ((green() >> 10) << 5) | (blue() >> 11));
               ^~~~~~

Solution, change line 125 as followed:
125 return (ushort)((red() & 0xf800) | ((green() >> 10) << 5) | (blue() >> 11));
