Actually, I built Expat on VS 2005 with 64bit portability warnings 
turned on,
and found one minor issue with the MUST_CONVERT macro. I checked in
this patch for xmlparse.c:

-#define MUST_CONVERT(enc, s) (!(enc)->isUtf16 || (((unsigned long)s) & 1))
+#define MUST_CONVERT(enc, s) (!(enc)->isUtf16 || ((s - NULL) & 1))

Some of the demo programs have integer conversion warnings as well, but it
should be safe to cast them away.
