I tried compiling this project using Atmel studio 6.2, and I got several problems.
First problems was that twi_master.h and .c was missing the needed #define:s so what I did to make it work was copying twi_master.h and .c from your quadcopter project.
The second problem is, which I guess, appears because we use different compilers.
Insteed of including .h in the main file file, I included .c, since the .h are included in these files.
It works like a charm. I used an Arduino Uno and MPU6050.
