Some different words on this whole subject - the way I see it.
I am not a lawyer - accept this as such.

First of all, there should be nothing in eCos which was derived [purely]
from a GPL environment, it has all been created either from scratch
(at Cygnus -> Red Hat, or by contribution).  Portions from other projects
are included, but still respecting their license (e.g. the FreeBSD stack)

IMO, the whole point of the GPL is about *rights*.  If I distribute
something which came from a GPL source, the recipient of that distribution
must have at least as much right to the code as I did, *including* any
changes or additions I might have made before distributing it.  The GPL
does not explicitly say that I have to give my changes back where I got
them, in fact, I can claim copyright on those changes and still distribute
them as I wish.  This is the case of code distributed by eCosCentric
(and indeed by Analogue & Micro, among others) - we've taken the public,
GPL+ex code, made changes, additions, improvements, etc.  Those who have
received distributions of such material have the right to use and change
the source code, but they don't gain ownership over it.

In the case of FSF projects, we have all agreed that whatever we contribute
into the pool becomes the property (copyright) of the FSF.  No other entity
(person, project or company) can claim ownership of such contributions, not
even the original contributor.
