 Changes between 0.9.4 and 0.9.5  [xx XXX 1999]

  *) Support for ASN1 "NULL" type. This could be handled before by using
     ASN1_TYPE but there wasn't any function that would try to read a NULL
     and produce an error if it couldn't. For compatability we also have
     ASN1_NULL_new() and ASN1_NULL_free() functions but these are faked and
     don't allocate anything because they don't need to.
     [Steve Henson]

  *) Initial support for MacOS is now provided. Examine INSTALL.MacOS
     for details.
