RE: [avr-gcc-list] WINAVR with GCC 4.3.3

I have spent a fair amount of time trying out various compiler options and this is what I settled on for large projects. A lot of suggested options made no significant difference in my projects however, your mileage may vary, so give em a try and see what happens: CFLAGS += -funsigned-bitfields -
