[avr-gcc-list] Linking and unused functions.

[Alan Kilian]

  I have been trying to use the avrlib from Pascal Stang
  <http://hubbard.engr.scu.edu/embedded/avr/avrlib/>
  on an AT90S2313 and at first, I thought the code was huge,
  but on further analysis, it appears that every function in
  a .o file gets linked even if it is never used.

  I edited lcd.c and timer.c to remove unused functions and the
  size of the hex file dropped dramatically. It's now about 10%
  of what it was before.

  I am not used to this behavior. I'm used to having only the
  functions actually called getting linked into the hex file.

  Is there something I'm doing incorrectly?

                          -Alan
