This function is used inside Windows headers. You can find the following
code in comutil.h in MinGW
inline _bstr_t::Data_t::Data_t(const char *s) : m_str(NULL),m_RefCount(1) {
m_wstr = _com_util::ConvertStringToBSTR(s);
}
But MinGW does not implement ConvertStringToBSTR, so QEMU should implement
this function.
We use _bstr_t in VSS-provided DLL, so this function is mandatory for us.
