 Thanks, this is useful because it does mean that your swig version is
recent enough. It would still be interesting if using --without-swig
doesn't solve the problem for you by chance, could you please try it?

 In fact they're present in all swig-generated files but are usually static
and are only extern #ifdef SWIG_GLOBAL. Exactly one swig-generated file
(swiglib.cpp) is compiled with this symbol on so it should contain the
definitions of these symbols.

 I don't think it's relevant. Including Python headers sometimes results in
this.

 I'd appreciate if you could look at swiglib.cpp generated by your swig
and grep it for SWIG_TypeQuery. If you can't make out why is it not
defined, just send the generated file to me and I'll have a look at it (or,
if worse comes to worst, I can always update to 1.3.21 which is in Debian
unstable...).

 Thanks!
