  25 /*  FUNCTION
  26         Adds a given library to the system's library list after checksumming
  27         the library vectors. This function is not for general use but
  28         (of course) for building shared librarys that don't use exec's
  29         MakeLibrary() mechanism.
  30
  31     INPUTS
  32         library - Pointer to a ready for use library structure.

  34     RESULT
  35
  36     NOTES
  37         Some old Amiga software expects that AddLibrary returns the
  38         library which was just added. When in binary compatibility mode
  39         AROS does this too.
