Unfortunately, the mess with names takes place.
he same interruption refers to:
   SIG_UART_DATA   - old AVR's
   SIG_UART0_DATA  - ATmega161
   SIG_USART0_DATA - ATmega162
   SIG_UART_DATA   - ATmega8 (modern uSart, the same as mega162)

Compiling, linking: misprint in an interrupt name will pass unnoticed.
Unused function will simply be added.
