Subject: [PATCH] Fix narrowing errors -Wc++11-narrowing

Clang 6.x finds these errors

    ../../../../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 ;
             ^

HRESULT causes the macro to be parsed as a signed long, so we need to force it
to be checked as an unsigned long instead.
