I think the point here is that 1) xmlpatterns doesn't build under any platform if exceptions are disabled (it won't "expose" exceptions in its API / propagate them, but it uses them internally); 2) WinCE *always* get exceptions disabled. While 1) is of course a design decision (so far, so good) what's the reason for 2)? Prevent a massive code expansion? Broken MS compilers?
