Summary: Win64 portability warnings

Initial Comment:
I am trying to get my software ready for Win64 
(AMD64 / IA64). Currently I'm using Visual Studio .NET 
2003 with /Wp64 switch enabled. However theres some 
missing typecasts in expat to make it compile clean.

Instead of waiting for someone to fix it I can probably do 
it myself but I'm only willing to if my changes will be 
considered for next release. I'm rather sure all the 
warnings will go away with apropriate typecasts. Please 
advise me how to continue.

I'm using the downloaded version of expat 1.95.8:

Ok, so I patched my local 1.95.8 distribution and created a 
diff file. All the patches I made, are __int64 to int typecast 
warnings. All of them were fixed by adding parentheses and 
adding a (int) typecast.

We'll certainly consider patches.  The best way to proceed 
would be to attach a patch to this bug report.
