Yes it's deliberate. (Turned out to be easy and convenient.) Yes it
goes beyond H98, so GHC types a few too many programs even in H98 mode.
I guess I should document it.

Hello,
I also couldn't compile it. I looked in the sources a bit, and at
least one of the problems was that that the wxHaskell wrappers used
'char' insted of 'wxChar', which I think causes problems if wxWidgets
is compiled with unicode support (as is probably the case with the
Debian library).
