No, this is not an issue. LGPL material can be relicensed as GPL by
anyone.

Yes, you're right. It's me being unsure of the convention. It should
be:

// Copyright (C) 1999 Jonathan Richard Shewchuk
//
// Modified by Johan Jansson 2006.

The modifications are quite limited (compiler issues, wrapping).

Formally it doesn't matter though, since if you write something you
have copyright to it, regardless if you write a copyright statement or
not. But it's good that we have a convention for tracking authors.
