WRT Licensing:

If you've got GPL code in the library then the whole thing is GPL (section 2, including the description beneath the page break). Once the whole distribution is under the GPL, you can't just remove those files that originally introduced the GPL. If you want to return the library to non-GPL status then you're going to have to roll back your CVS changes of the entire library to the point at which the GPL components were added and develop from there. You can't just 'take them out again', because by including the GPL components you've placed the entire distribution under the GPL.

The standing of a library the moment that you incorporate a GPL component into it is very clear - it and everything that links against it is under the GPL. Once you've started to use the GPL, the fact that there are LGPL and BSD license components in it is pretty much irrelevant. You still have to say that there are parts under those licenses (because that's what those licenses say you must do), but the freedom to do what you like under those licenses is subsumed under the all encompasing "thou shalt honour no god before me" GPL (section 4).

Whilst I'm sure that the discussion of the issue of incorporating GPL sections into the library was long and difficult between the various developers and users of UnixLib, it's hardly a trivial thing. I don't use UnixLib, so maybe I missed it, but with such a large change in the license for a library like that I would have thought that I would have at least heard about it...
