syslog-ng can operate in both 2.x compatible mode and 3.x compatible
mode. The '@version' header in the syslog-ng configuration file controls
which one is used.

If someone has no version header, syslog-ng assumes it wants syslog-ng
2.x compatibility.

There was no macro related changes in the 3.0 series and still the
format with the MSGHDR is the correct one.

Can you show the user posting that states MSGHDR is the wrong approach
to do? I might be able to help troubleshooting it.
