I'm not sure that there is anything specific needed where /*64*/ 
comments exist, the tool would have a lot of work to translate 
many types and not just a single cast.

But I did find where there is more work. The segfault pointed to:

     org.eclipse.swt.widgets.Display.Display.windowProcFunc3()

Which is defined as:

     private static extern(C) int /*long*/ windowProcFunc3 (int 
/*long*/ handle, int /*long*/ arg0, int /*long*/ user_data) {

which is assigned as:

     GCallback windowProc3 = cast(GCallback)&windowProcFunc3;

Where GCallback is defined as:

internal.gtk.OS.d
     public alias org.eclipse.swt.internal.c.glib_object.GCallback 
GCallback;

     alias _BCD_func__2331 GCallback;
     alias void function() _BCD_func__2331;

I don't understand why it is cast to a function which takes no 
arguments, but suspect that fixing the signatures for /*long*/ is 
a good direction.
