Ok, consider me convinced on this part. I will add portable RFC3164 support to Boost.Log, as it will help to route log records better.
It turned out implementing a simple rfc3164-based logger is not all that difficult, really. I guess the biggest effort would be to integrate it meaningfully into Boost.Log. Anyway, here's the source code, in case any finds it useful.
