That's an include file for the building of the unix Midi VM plugin. 
You'll need to know how to build the VM to play around with it. There 
are plenty of descriptions available if you'd like to do that. It's not 
hard if you're a C programmer and know linux.  I was hoping that others 
might speak up, especially Florian, about the status of the file, before 
you dive into this.
