This is generated in CoinMpsIO.cpp, I believe. I don't know of an easy way
to disable it. You can modify your copy of the code to disable it.

Comment out line 65 of BB_tm.cpp

This is an irritating message from Clp, I agree. If someone could tell
me how to disable it, I would be happy too. I am able to disable
some of these by using:

   OsiClpSolverInterface * clp = new OsiClpSolverInterface;
   clp->messageHandler()->setLogLevel(0);

in BB_lp::initialize_solver_interface(). I believe that this should be
disabled if log level is zero, but it is not always so.

Set BCP_TmVerb_FinalStatistics 0
