Some systems stringify an errno value of 0 as "no error".  A few things could
have caused this:

1) Something might have set errno to 0 between the failure and the error being
printed.  Many I/O operations will do this, some at the OS level.

This could be in the CLEANUP_ERROR_HANDLER or REPORT_ERROR or even inside
xmlCreateFileParserCtxt itself.

2) The failure may not have been the result of an I/O failure causing errno to
never have been set.

Is there a guarantee that xmlCreateFileParserCtxt() sets errno reliably?
