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.
