0x80042308 or 0x80042308L looks interpreted as unsigned 32-bit int in
mingw gcc. And in mingw headers, these errors are defined like:
#define VSS_E_OBJECT_NOT_FOUND _HRESULT_TYPEDEF_(0x80042308)
where _HRESULT_TYPEDEF_ is a cast to HRESULT (signed 32-bit int).
Maybe I should add casts like (HRESULT)VSS_E_... to avoid the warning....
