ARC 1.1 GCC sample code

Use WinAVR distribution found at www.avrfreaks.net

Note, that enabling STDIO for printf support will add ~2400 bytes to
final application.  Sizes, below, do not include "printf" support.  Not all samples
use serial I/O.  Most, however, will print diagnostic info when USE_STDIO is defined.

The arclib_10.c (helper functions) consume 220 bytes even though all parts are not
used.

The makefile variable "TARGET" needs to be set to the name of the sample you want to build.

make            - builds the current "TARGET"
make clean      - deletes everything but source
make burn       - will program the chip
make TARGET=XXXX - will build "XXXX.c + arclib_10 and make an executable.      
make all        - will build all targets

Most programs, below, are ported copies of the BASCOM samples.

Sample		    Size	Description
-----------	    ----	----------------------------------------------------
flashled.c	    394	Very simple C program to flash green Program LED
flashled_FSM.c	422	Same flasher, but implemented as a Finite State Machine
switch.c        394 Very simple C program to read an input and set an output (LED)
ADCtoPWM.c 	    510	Read Left/Right SHARP ADC input and set Left/Right PWM output
minisumo.c	    582 simple mini-sumo code identical to the BASCOM sample
