X-Git-Tag: krb5-1.0-beta6~1896
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=a12e104e3911c694bd56fe3519e14ae63e995611;p=krb5.git

Remove backward compatibility code for Kerberos V3 (!) which was
causing problems for shared libraries.  Library code shouldn't try to
reference global variables defined by the calling application!
