what is the --msg4 option?

I'm using Omnet++ and inet as a library. I get the error, whenever I try to build the Project, Type declarations aren't needed with imports, try invoking the message compiler in legacy (4.x) mode using the --msg4 Option I don't know what that means. Can anyone help? Or tell me at least what that legacy means? Thanks in Advance.

Starting with OMNeT++ 5.3 we have made certain backward incompatible changes to the message compiler. That was by default turned off (--msg4 default), but could be enabled with the --msg6 options. INET uses msg6 compatible mode for some time now (since INET 4.0) and it forces it by adding the --msg6 option in the makefiles. If you add code to INET 4, you must also adhere to the new syntax:

See further details about the change in the ChangeLog: https://github.com/omnetpp/omnetpp/blob/master/src/nedxml/ChangeLog#L298

OMNeT++ 6 will default to the msg6 mode.
