Make throws Error 2: clock_div_1 undeclared

[sanotronics]

Hi! I downloaded the last version yesterday and tried recompiling to rename my device and I had 2 different issues.
I am using windows 7, 64 bit, and "LUFA-140928"

The first one was that I had to erase every other project from the lufa Projects folder, since I was getting an error at Benito.c xD

The second one was with the file "arduino-midi.c"

I got that error on line 74, so I checked and with some search I found this:
http://fab.cba.mit.edu/classes/863.14/people/andrew_mao/week11/

Apparently "clock_div_1" is not defined in avr/power.h for Atmega16u2, so for make to work, and still disable the clock prescaler you need to comment line 74 and add this code:

CLKPR = (1 << CLKPCE);
CLKPR = (0 << CLKPS3) | (0 << CLKPS2) | (0 << CLKPS1) | (0 << CLKPS0);

That works!

Thx for hiduino guys!
