People build commercial applications all the time under Linux. These
applications implicitly call the Linux kernel, and perhaps explicitly
call on a variety of commands (which are really applications) like "mv",
"cp" and so on. Yet these commercial applications are not under the
GPL. I think Luca's situation is similar.
Another example, a lot of ISP providers are able to offer Jabber, MySQL
and other services that are GPL'd. Customers are invited to write
(non-GPL'd) applications that make use of these services. Such as an MS
Access and Excel application that links to a MySQL instance on an ISP
provider.

Glpsol is linked to the glpk library, so your program is linked to it
indirectly.

Why do not implement your program under GPL? It would be in the spirit
of GNU software.
