* Description : Definition of platform independent data
* types and constants
*
*
* The following platform independent data types and corresponding
* preprocessor (#define) constants are defined:
*
* defined type meaning corresponding constants
* ----------------------------------------------------------
* Char character (none)
* Bool boolean true, false
* Word8 8-bit signed minWord8, maxWord8
* UWord8 8-bit unsigned minUWord8, maxUWord8
* Word16 16-bit signed minWord16, maxWord16
* UWord16 16-bit unsigned minUWord16, maxUWord16
* Word32 32-bit signed minWord32, maxWord32
* UWord32 32-bit unsigned minUWord32, maxUWord32
* Float floating point minFloat, maxFloat
*
*
* The following compile switches are #defined:
*
* PLATFORM string indicating platform progam is compiled on
* possible values: "OSF", "PC", "SUN"
*
* OSF only defined if the current platform is an Alpha
* PC only defined if the current platform is a PC
* SUN only defined if the current platform is a Sun
*
* LSBFIRST is defined if the byte order on this platform is
* "least significant byte first" -> defined on DEC Alpha
* and PC, undefined on Sun
