I'm trying to build gcc for use with an AVR micro controller and avr-ada, and I've hit a roadblock caused by my regular compiler being too picky about the version I needed for the AVR. I get the following warning, which in turn causes the gcc or make to report an error:

gcc -c -g -O2 -gnatpg -gnata -nostdinc -I- -I. -Iada 
  -I../../gcc/ada ../../gcc/ada/exp_ch5.adb -o ada/exp_ch5.o
exp_ch5.adb:177:16: warning: function "Has_Address_Clause" is not referenced
make[2]: *** [ada/exp_ch5.o] Error 1
make[1]: *** [all-gcc] Error 2
make: *** [all] Error 2

Is there a way to instruct gcc or make to not fail on warnings?

Try make -k instead of just make. That will 'continue' rather than stop.
