What version of expat do you have? I have 1.95.8; you can look in
/usr/include/expat.h for this:

   #define XML_MAJOR_VERSION 1
   #define XML_MINOR_VERSION 95
   #define XML_MICRO_VERSION 8

Also in expat.h, I see this:

   XMLPARSEAPI(int) XML_GetCurrentLineNumber(XML_Parser parser);

So it's "int" there. But your warning was about type "XML_Size",
which according to your patch maps to long int:

"XML_Size" doesn't even appear in any of my expat header files :-).
So are you using a different parser with an almost-but-not-quite-same
API, or just a different version of expat?
