I hadn't actually included exception.i in my code. It took some hunting
around in the swig libraries to determine that one of *those* libraries
were including it -- the std_*.i ones, I believe -- but found my local
one instead. For example, find/grep exception.i in the swig library
results in (among others):
./std/std_basic_string.i:1:%include <exception.i>
./std/std_container.i:2:%include <exception.i>
./std/std_except.i:17: %include "exception.i"
Actually, there are quite a number of them that include "exception.i"
rather than <exception.i>.
In any case, Marcelo, thanks for pointing this out.
