I assume that the last sentence there is the main reason for your
seeking OSI approval for the license. But in that case, why not simply
stop referring to 'the eCos License 2.0' as though it were a special
license and instead characterize eCos as being licensed as 'GPLv2 or
later' with a permissive exception? I've encountered other projects
using similarly-worded GPL exceptions but to my recollection those
projects characterize themselves as being GPL-licensed.

Thanks for pointing to the wxWindows license -- however the OSI's
approval of that license seems to be from the late 2002 timeframe,
before the rise of concerns about license proliferation and 'vanity
licenses' and such.
