Ethernet2.h and MySQL_Connection.h

Hello,
I have an error in the compilation when using the following libraries: 

///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
#include <SPI.h> // for Ethernet
#include <SD.h> // for FRAM to work

#include <Ethernet2.h> // use Industruino version
//#include <Ethernet.h> // FOR TESTING

#include <MySQL_Connection.h>
#include <MySQL_Cursor.h>


Test with the ethernet.h library, the compilation goes all the way.
Hands, of course, the ethernet.h library does not work with lndustruino 

Sincerely

hi, there is a header file in the mysql library that also includes the Ethernet.h library; i think if you change that to Ethernet2.h it may work:
