source: trunk/third/moira/util/et/error_message.c @ 23740

Revision 23740, 1.7 KB checked in by broder, 15 years ago (diff)
In moira: * New CVS snapshot (Trac: #195) * Drop patches that have been incorporated upstream. * Update to build without krb4 on systems that no longer have it. This doesn't build yet on squeeze, which lacks a krb4 library, but I'm committing now before I start hacking away at a patch to fix that.
