CHANGE LOGS:
V7.03 - March 26th 2007
  [ Vista compatible licensing engine ]
  IDE
    - Added S12XDP512 to device list
    - Added a "CPU Type" radio group for "Custom" device.
    - expanded memory uses either "-maps1" or "-maps12x" in linker flags,
      depending on the CPU type.
    - Changed device names from HC... to MC...
  Preprocessor
    - __FILE__ now expands to filename without the path component
  Assembler
    - XGate support broke some processing in the CPU12 instruction processing.
      Fixed.
  Linker
    - -maps1 now maps 0x4000.0x7FFF as last_page-1
    - Added -maps12x, maps 0x4000.0x7FFF as last_page-2

V7.02 - Dec 21st, 2006
  Minor licensing changes
  IDE
    - Added tools to allow sending email for licensing, support etc.
  Compiler
    - All known bitfield problems fixed.
  Assembler
    - Preliminary XGate support in the assembler. Email us for short
      HOWTO file if needed.
  Header Files
    - Some files were missing PORTA, PORTB, DDRA and DDRB definitions

V7.01 - Oct 16th, 2006
  Compiler
    - When flipping a branch during the optimization pass, the 
      optimizer was using wrong branch instructions. This may show up
      as a loop executing one less time than it should.
  Library
    - itoa/ltoa/print %d/%ld now print -32768 and -2147483648 (e.g. high bit
      on) instead of -0

V7.00 - September 28th, 2006
V7 Comparing to ICC12 V6
  - X register is no longer preserved by a function call!!! Bitfield code 
    may be broken. 

  C Preprocessor
    - Complete NEW C99 conformant C preprocessor (VARARGS macros etc.)

  IDE
    - Numerous major and minor usability improvements over V6, including
      full Mouse Wheel support.
  IDE/Linker
    - "S2 record only" option emits only S2 records, for better compatibility
      with SRecCVT (e.g. 0x4000-0x7FFF maps to last flash page-1 extended
      address)
  Compiler
    - Rewritten code generator. Code should be ~5% to 10% better. As this is 
      still in development, please email support@imagecraft.com with any 
      suboptimal code you notice.
  Libraries
    - FP lib is now fully reentrant and much faster compared to V6
  Header Files
    - Header files for all HC12, S12 devices in production
