You certainly can link with it, and then your code becomes GPL.
No, the code is code. It is an artifact. The GPL is a legal
document. The legal document says what rights you have to the
copy you received and what requirements that follows it. You are
allowed to modify it and do anything you want with it that is
covered under fair use. This varies between jurisdictions.
The license primarily comes into effect when you _distribute_ or
_publish_, because the legal precedent for putting restrictions
on distribution and publishing is much stronger. And WIPO is much
more clear there.
So, if you build websites for a third party you can use GPL
without redistribution by writing the contract in such a way that
the third party is using your service. Meaning, you run the
software. So circumventing the GPL isn't all that hard if you
The AGPL also affects publishing as a service, so it makes such
arrangements much more difficult.
