I agree mostly. Using 
#include "perl.h"
#include "XSUB.h"
#undef XSPROTO
#define XSPROTO(name) void name(pTHX_ struct cv* cv)

instead of 
#define CV __perl_CV
#include "perl.h"
#include "XSUB.h"
#undef XSPROTO
#define XSPROTO(name) void name(pTHX_ __perl_CV* cv)
#undef CV

[download]
is much more elegant and better. But both variants should work.

However SWIG_init is declared with two parameters.

In 'SWIGEXPORT void SWIG_init (pTHXo_ CV* cv);' macro 'pTHHXo_' expands to 'PerlInterpreter*,'.

With the comma at the end there are suddenly two parameters.
