Among other things, my C/C++ code calls a user-defined Python
function. The return value of this function is a SWIG wrapped object
and I need to obtain a C++ level pointer from this object. I defined a
utility function to unwrap this object (line 1360 of
http://simupop.svn.sourceforge.net/viewvc/simupop/trunk/src/utility.cpp?view=markup)
which calls PySwigObject_Check to check if the 'this' attribute is a
SWIG-wrapped pointer.

I am currently using SWIG 1.3.36 and uses PySwigObject_Check defined
in its generated swigpyrun.h. When I tried to use SWIG 1.3.39,
PySwigObject_Check (and other functions) are no longer defined so I
have to use a macro to differentiate the different versions of
swigpyrun.h. Unfortunately, SWIG_VERSION is only defined in the
wrapper files, not in swigpyrun.h.

It appears that I need to move all such functions to my wrapper files
where SWIG_VERSION is defined. However, it makes sense to me to also
define SWIG_VERSION in swigpyrun.h.
