Hello jdv!

Lets see if I got this correctly:

  1. XSUB.h is included in line 745 of pwiz_swigbindings_wrap.cxx, defining typedef struct cv CV and macro XS.
  2. cv.hpp is included in line 1862 of pwiz_swigbindings_wrap.cxx, defining a different struct CV.
  3. the XS macro from Perl is used first in line 2149 of pwiz_swigbindings_wrap.cxx

It is ugly, but the preprocessor can help to move the conflicting identifiers around. To do so I would manually modify the file pwiz_swigbindings_wrap.cxx and insert this line before
#define CV __perl_CV
and these ones after
#undef XSPROTO
#define XSPROTO(name) void name(pTHX_ __perl_CV* cv)
#undef CV
line 745.

I checked this roughly with the following C code: 
#define CV __perl_CV
/* beginning of include XSUB.h */
struct cv {
        int i;
};
typedef struct cv CV;
#define XSPROTO(name) CV name
/* end of include XSUB.h */
#undef XSPROTO
#define XSPROTO(name) __perl_CV name
#undef CV

struct CV {
        char c;
};

XSPROTO(x);

int main()
{
        struct CV y;
        x.i = 0;
        y.c = '!';
        return 0;
}
