Just wanted to report the following observations in generated code.
Target: __AVR_ATtiny85__Version: AVR gcc 4.6.4Optimization level: -Os
C source -- uint16_t sum_adc; uint16_t analog; uint16_t
adc_buffer[64]; uint8_t adc_index;... sum_adc += ADC; sum_adc -=

linker flags are used.
I guess this is a wishlist item really: it would be nice if using pri
