If you changed the declaration to the moral equivalent of uint64_t (C99) then people with old code would get an integer truncation warning when they recompile against the new version.  For Windows if you change the default DLL name most people will not fall into running previously compiled code against the new version.  All reasonable to do on a major version change.

Actually, Rolf Ade suggested this as a feature request.

Now here are the issues:
- Expat 2.0 is supposed to be just the final, stable release of the 
1.95.x series.
  So introducing such a change that late might not seem appropriate.
- On Windows, the library names have never had a version included.
  So, one solution could be to make it a compile time option, and have
  the default binary use the old compatible 32bit values. Later - post 
2.0 - we could
  remove the compile option and make 64bit values the default.
