  62 SYNOPSIS

  64
  65 DESCRIPTION
  66         This routine is called before any other BFD function using
  67         initialized data. It ensures that the structures have
  68         been initialized.  Soon this function will go away, and the BFD
  69         library will assume that <<bfd_init>> has been called.
