If you take care to name the original authors and the authors who did
modifications and the dates of the modifications, it also will help you
always to know exactly how you build your own version of software,
that's done by a GPL licensed software bundle. Some day you might get
troubles by doing the debugging and then you might notice, that you
can't exactly remember at what time some parts of the used GPL source
code done by other authors was changed, so you might get problems to
narrow down some problems.
