Something like this might work:

inline const char *dlerror(void)
{
     static char errStr[512];
     DWORD       errCode = GetLastError();

     if (!FormatMessage (FORMAT_MESSAGE_FROM_SYSTEM |
                         FORMAT_MESSAGE_IGNORE_INSERTS |
                         FORMAT_MESSAGE_MAX_WIDTH_MASK,
                         NULL, errCode,
                         MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT),
                         errStr, 511, NULL))
         sprintf(errStr, "dlopen()/dlsym() caused error %d", errCode);

     return errStr;
}


and if it doesn't, there is always #define dlerror() ""  :-)
