commit 56398ab7b7e619a7fc23315e6a5960ccbcfadbe7
Author: Murray Cumming <murrayc murrayc com>
Date:   Thu May 7 18:00:24 2009 +0200

    Fix the build without exceptions, hopefully.
    
    * libxml++/parsers/textreader.cc: check_for_exceptions():
    Add an ifdef so that this should build with exceptions disabled,
    though there is no alternative API yet. Noticed by David King.
