gcc 4.1 is more strict than previous versions, and
produces some compiler warnings with stable xdvi. As

Actually I don't expect that this is a big thing,
because xdvi is already used on such platforms, and the
actual compiled code shouldn't be changed by the
warning. But it might still make sense to look into
this. Here's a build log with gcc-4.1:
(search for "cast from pointer to").
