Firstly, in today's world, your vendor is being pretty silly :-(

I am not a lawyer (IANAL), so treat everything I say carefully.
If you are concerned, contact a good Intellectual Property lawyer
before you distribute anything.

I do think if you structure things carefully and don't name
anything so that it will expose the secrets, it will probably be
OK.

Secondly, the GPL only says that you need to distribute the source
code to those to whom you distribute the code (executable, etc).
Presumably those folks would have similar information available
to them as well, so there's no leaking there either.

Finally, in order to port eCos, you *need* to have a GCC port
(there's just too much in eCos that depends on some special
GCC support).  If this exists, how do they handle it since
they'd be dealing with the same sensitive information?
