As far as I understand it, the action of linking is not a violation.
Distributing the "linkage" might be a violation depending on the license
used.

For example:

I can modify a piece of GPL'd code to my hearts content, link it to my
proprietary code, use it for years, all without violating the GPL. A
violation would be if I distribute the combination as proprietary (non
GPL) software.

Comments?
