Look, I'm having a real battle with GNUARM.  I just can not get rid of
all of these multiple definition include problems between device.c and
board.c, both of which Atmel wrote.

My map file with the cross reference table looks like this:

                                                  main.o
....
etc.
....

All of those functions are defined as "inline".  The original make
file used -std=gnu99 (came from WinARM) which in my reading kind of
rules out the inlines, so I reverted the flag to -std=gnu89,
everything as you can see compiles but the dam thing just won't link.
