Mk4py (the MetaKit wrapper) uses throw / catch. We just recently had to
get rid of all cases where the throw and catch were at the top level. If
the throw is in a called routine and catch in the caller, it works fine. 
But top-level throw / catches stopped working recently (at least with gcc).

AFAIK, the advise about compiling Python with C++ only applies if your
C++ uses static objects. Mk4py doesn't, and we've never heard of anyone
having to recompile Python with C++ to get it working.
