This might not work in the place of loadable modules where you have to deal with many catalogs etc. How about a different proposition, we use the message format char * as the message id, potentially sending the text over the first time it's used. This could still break if we unload a module and a new one is loaded in its place, but that sounds fixable. > ... that's what I have so far.

Moving a lot of work to the log postprocessor is good. -- Ondřej Kuzník Senior Software Engineer Symas Corporation http://www.symas.com Packaged, certified, and supported LDAP solutions powered by OpenLDAP
