What makes them say that? Is it a moral or legal issue?

Why would you want to do this? IMO the strength of a GPL license is
dependent to some extent on having multiple copyright holders. Personally,
i would be reluctant to release code under such an arrangement. (Not that
my vast contribution counts for anything. ;-)

Are you saying that there cannot be a WinCE version at all without using
proprietary libraries? If this is the case, i think there is a strong case
for applying the 'OS libraries' exception to them, even if they aren't
offically part of the OS.

You're hoping. :-) (Besides, if he does, make him free his code rather
than shackle Sword. 8^)

If you're that worried about it, switch the whole thing to LGPL, or use the
'special exception' noted in the FAQ that allows linking to a particular
list of proprietary libraries.
