Few minor issues

[vertexodessa]

Revision 1bc7069 (to make sure all the lines are correct)

Incorrect variable assignment:

  ret = inet_pton(ss.ss_family, host, addr);
  if (ret != 1)
  {
    int err = errno;
    rtLogError("failed to parse: %s as valid ipv4 address", host);
    error = rtErrorFromErrno(err);
  }
  error = RT_OK;

"error" is used incorrectly. it will always be equal to RT_OK.

pxMatrix4T class implements copy ctor but not "operator ="

Not sure if all of these issues still persist, but would be good to review and clean up.
