Copter V3.1 Won’t Compile

I needed to lower the AUTO_YAW_SLEW_RATE parameter and tried to compile 3.1 but it told me that the generated binary was too long. V3.0.1 worked OK. I have the modified compiler (1.0.3) that I get last spring. Has their been any changes lately to the compiler? What am I doing wrong? I am running Windows XP.

you need to install gcc 4.7.3 to be able to build the code small enough for APM2.5 with the current selected feature set,.
