If you aren't sure what they are - javascriptcore and webcore have their origins in KHTML, no matter how much of it has been replaced by Apple it's still from that, gcc and gdb are well known GNU parts. CCtools seems to have Darwin origins, they chose to open source it.
This is a step forward, but they are still violating the license. Those releases do not have the necessary information to build a new copy, as required by the LGPL: no project IDE (Xcode) files and no makefiles for the iPhone.<p>And, as saurik mentions here (<a href="http://news.ycombinator.com/item?id=2523786" rel="nofollow">http://news.ycombinator.com/item?id=2523786</a>), they do not even release the full source code! Even if you ignore the point about building your own copy, they are still violating the LGPL: releasing the code to those "WAK" classes is <i>not</i> optional.
