  21 /* Functions xInitCode and xExitCode give you the ability to do things on
  22    opening and closing of library. These functions are called by init
  23    routine or by Expunge. Init is the only funtion, that is allowed to set
  24    a value for an global variable. The library base pointer is on stack!
  25    If xInitCode returns not zero, the init function fails and thus the
  26    library cannot be opened!
  27
  28    The xInitCode function can for example be used for processor type checks:
  29    the <flag> place holder may be any of the following values:
  30    CPU's: AFF_68010, AFF_68020, AFF_68030, AFF_68040
  31    FPU's: AFF_68881, AFF_68882
  32    NOTE: for better processors (e.g. AFF_68030) the lower bits are set also
  33    (AFF_68020 and AFF_68010), so you only need to check one value!.
  34    The flags for CPU and FPU can be used both with (AFF_CPU | AFF_FPU).
