GTK2 GdkNativeWindow compilation errors

I compiled pike on a system that has a version of GTK2 that includes a =
typedef for GdkNativeWindow that the GTK2 code doesn=E2=80=99t =
specifically address. The compiler (a recent clang) errors on these =
implicit casts to and from GdkNativeWindow (which I believe resolves to =
a platform dependent pointer) and integers that the pike glue deals =
with. I was able to solve the errors but wanted to get some feedback =
before I commit it, as I get the impression that GdkNativeWindow was =
something added somewhere along the way, so there probably may need to =
be some configure glue added. Is anyone using the GTK2 module that might =
be able to test these changes to see if they cause problems elsewhere? =
Or should I commit a best-guess fix and wait to see how pikefarm reacts?
