In that case this has nothing to do with gettext capabilities; gettext does not process format strings but simply translates one format strign to another, and if a program is using non-portable format strings, it's going to break whether it's using gettext or not. So I don't think it's relevant to this discussion of whether _gettext_ is compatible. Rich
