Dave, maybe a minor point at this point, but the engine wasn't supposed
to have error messages in it; if there's an error condition, then
there'd be a code that could be queried using xaccGetError() or some
such thing.    This allows error handling by the engine users to be 
done in a try-catch-throw block style.

/* try block */
xaccClearError();
xaccDoThis();
xaccDoThat();
xaccDoOther();

/* catch block */
if (xaccGetError()) {
   printf ("whatever\n");
}
