GWindows, CLAW, and Windex are all strongly typed at the user code
level. One core routine does all the unchecked conversions from the
Win32 API types.
GtkAda is less strongly typed, because the user has to figure out what
generics to instantiate to get the marshalling right. That's one
reason I'm giving up on it.

Which is how GWindows, CLAW, and Windex do it. Great minds do think
alike ;).
