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:

It seems this patch should work on other platforms as well.
I'll have a look at this together with issue # 1284386.

I don't understand why anyone hasn't looked at the patches 
yet? Sooner or later you will get more of these Win64 x64 
requests because it's soon to be released as final and then 
people will want to write software for it.

The patches I submitted are quite trivial which you will see 
when looking through them.

Thanks.

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.
