That is correct, but you must understand we're talking about the reverse 
direction.

A GPL application is allowed to link to a system library even if that 
system library is closed source. That's how there are GPL applications on 
Windows.

However, a GPL system library is not allowed to link (or be linked) to a 
closed-source application. That's why the system libraries on Linux are 
actually LGPL (and one of the reasons why we chose to change the licensing 
for Qt -- we want Qt to become one day "system library").
