This fixes the build with Clang 6.0:
../../../../CPP/Windows/ErrorMsg.cpp:24:10: error: case value evaluates to -2147024809, which cannot be narrowed to type 'DWORD' (aka 'unsigned int') [-Wc++11-narrowing]
case E_INVALIDARG : txt = "E_INVALIDARG"; break ;
^
../../../../CPP/Common/MyWindows.h:89:22: note: expanded from macro 'E_INVALIDARG'
#define E_INVALIDARG ((HRESULT)0x80070057L)
^
The HRESULT cast in the macro causes the value to be read as signed int.
