I am not a great C++ person so as I am building my first C++ extension I am
seeing this error which I don't understand
> _aggstate.obj : warning LNK4197: export 'init_aggstate' specified multiple
times; using first specification

I looked in the preprecessor output(_aggstate.i) and see this single occurrence
of aggstate_init
#line 1191 "_aggstate.cxx"
extern "C" __declspec(dllexport) void init_aggstate(void)
{
aggstate_init();
}
is this some feature of C++ or is there a real issue here?

*PS this also occurs when compiling with 3.7, but there the initializer
function is PyInit__aggstate
