I expressed my question very badly, so you may have misunderstood.

I was referring to the problem of programmatically disabling the output.

You already answered positively as far as recent versions of glpk are 
concerned and that was fine.

I know, but I would like to also know if there are other ways of doing 
the same in older versions of glpk. The reason for being still 
interested in these outdated versions is that I want to write my code so 
as to be as much as possible backward compatible since, e.g., the rpm 
currently distributed with Fedora Core 6 is glpk-devel-4.13-1.fc6; 
similarly, for Fedora Core 7, we have glpk-4.15-1.fc7.
(NOTE: here I mean the rpm's that are automatically obtained by using 
tools such as pup, the package updater available in Fedora.)

Thanks again,
Enea Zaffanella.
