accept pointers to SourceLocation objects, so as long as the runtime's definition matches the structures the compiler emits, things work.<span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D"><o:p></o:p></span></p>

and my C code should can directly access the data in the SourceLocation C++ class object. OK, I know how to do it now.<o:p></o:p></span></p>
