 Unless I'm missing something, this does look broken.  Here are the 
snippets from the post-processed translation unit
of EventHandler.h:

 typedef void* ent;
 typedef uint32 SourceID;
 struct SourceIDList : BaseList { void insert(SourceID a) { 
BaseList::insert(ent(a)); }

 Needless to say, on a 64 bit architecture casting a 32bit into to a 
64bit value is a mistake.

 I'm assuming this code was written before templates became practical in a
performance sensitive environment.  Perhaps its time for an upgrade?
