Re: building from urlwrite gives undefined reference to `_errno()' (MinGW build 3.3.50+)

[Tatsuro MATSUOKA]

Hello
If

  std::string lasterror (void) const
    {
      CURLcode errno;

      curl_easy_getinfo (rep->handle(), CURLINFO_OS_ERRNO, &errno);
      
      return std::string (curl_easy_strerror (errno));
    }

in urlwrite.cc were modified as

  std::string lasterror (void) const
    {
      int errno;

      curl_easy_getinfo (rep->handle(), CURLINFO_OS_ERRNO, &errno);
      
      return std::string (curl_easy_strerror ((CURLcode)errno));
    }

The link errors below were disappeared.

However, the modification is perhaps a not proper modification. Can anyone give 
me suggestions or
advises?

Regards

Tatsuro
