Thanks for your comments.  I think that the GLPK manual should be adjusted
in order to reflect the above.  At two different places, I read:

    Message level for terminal output:
      GLP_MSG_OFF --- no output;
      GLP_MSG_ERR --- error and warning messages only;
      GLP_MSG_ON  --- normal output;
      GLP_MSG_ALL --- full output (including informational messages).

Could you please propose a patch to be applied to the Debian package such
that the bug report can be closed?

Thanks,
