title: warning undefined reference to arduino due in multiwii
body: <p>I try to compile multiwii code on DUE <a href="https://github.com/HefnySco/MultiWii_DUE" rel="nofollow">https://github.com/HefnySco/MultiWii_DUE</a></p>
  
  <p>I keep getting </p>
  
  <p><pre><code>C:\Users\MCA9A~1.HEF\AppData\Local\Temp\build4616066844745192383.tmp\EEPROM.cpp.o: In function <code>eeprom_write_block(void*, void*, unsigned int)
  C:\Users\MCA9A~1.HEF\AppData\Local\Temp\build4616066844745192383.tmp/Sensors.cpp:307: warning: undefined reference to</code>Wire'</code>
  </pre></p>
  
  <p>I made a separate project to simulate the case and created file called class1.cpp and included Wire_DUE.h and then called it from the main project class Sample1.cpp and it worked using the very same Wire_DUE code.</p>
  
  <p>Kindly advise</p>
