Syslog would certainly do the job, but seems a bit of overkill unless
you're trying to collect logs from several zsh at once to see how they
interact.

I probably didn't understand your question properly before.  I think
what you want is to sprinkle some calls to dputs(ERRMSG(...)) around
the functions you're interested in.

If you do use syslog, using ERRMSG(...) will add helpful stuff like
the file name and line number.

For both dputs and ERRMSG you need to compile with DEBUG defined to the
preprocessor.
