OK.

This is definitely not fine enough for debug and trace. I may very  
well just want to look at the osol parser in detail and not be  
confused by output from the osil parser; same for osrl.

Again, I can see trouble with the debug and trace levels. I am not  
overly worried about cross-contamination of different solver  
interfaces, since typically only one will be active for any problem,  
but I might want to look only at the ampl to OS interface in great  
deal without worrying about the handshake with Ipopt, for instance.

This is probably OK.

Fine as well.

Ipopt uses a good deal more than that. From IPJournalist.hpp:

   enum EJournalLevel {
     J_INSUPPRESSIBLE=-1,
     J_NONE=0,
     J_ERROR,
     J_STRONGWARNING,
     J_SUMMARY,
     J_WARNING,
     J_ITERSUMMARY,
     J_DETAILED,
     J_MOREDETAILED,
     J_VECTOR,
     J_MOREVECTOR,
     J_MATRIX,
     J_MOREMATRIX,
     J_ALL,
     J_LAST_LEVEL
   };

I am not saying we need to copy Andreas, I just want to make sure that  
the information is out there. Also, I would recommend that the debug  
level be hidden behind /ifdef`s for efficiency reasons.

Cheers
