openssl/crypto/x509v3/x509v3.h
Dr. Stephen Henson 175b0942ec More extension code. Incomplete support for subject and issuer alt 
name, issuer and authority key id. Change the i2v function parameters
and add an extra 'crl' parameter in the X509V3_CTX structure: guess
what that's for :-) Fix to ASN1 macro which messed up
IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
