CHANGE LOGS:
V7.20 Jan 10th, 2009
  [ Enabled -NC Non-Commercial Use license]
  IDE
    - For XMega128, add the -xcall flag so 22-bit relocation will be used
      for CALL instructions since the bootloader flash is beyond
      the 128K byte boundary.
  Compiler
    - Fixed a very obscure bug with ldd offset expansion.
    - For XMega, 16 bits writes are now done low byte first to conform to the
      IO register access requirement
    - Faster code to load a constant into longs.
