               Implementation

   16.09.2002  -as
               To save code space the functions AmiSetByte and AmiGetByte
               are replaced by macros. For targets which assign u8 by
               an 16Bit type, the definition of macros must changed to
               functions.

   23.02.2005  r.d.:
               Functions included for extended data types such as UNSIGNED24,
               UNSIGNED40, ...

   13.06.2006  d.k.:
               Extended the interface for EPL with the different functions
               for little endian and big endian
