Help with configure option

[Alistair Leslie-Hughes]

Hi,
  I need to add an option, HAS_TEXTCONCAT_BUG to the configure script 
to check for a bug in libxml.  What file(s) do I have to change?

The file attached is an example to test for this issue. (returns -1 if 
the error exists)

Best Regards

int main()
{
    xmlNodePtr nodeComment;
    int nRet = 0;
    
    nodeComment = xmlNewComment("This is a Comment Node");
    
    nRet = xmlTextConcat(nodeComment, "Hello", 5);
        
    return nRet;
}
