Calling C++ code with pointer** argument

[abad via Digitalmars-d-learn]

D source:

extern(C++) void thisWorks(const char* test);
extern(C++) void doesNotLink(const char** test);
void main() {
    char* baz1;
    char** baz2;
    thisWorks(baz1);
    doesNotLink(baz2);
}

CPP source:

#include <stdio.h>

void thisWorks(const char* test) {
    printf("hi\n");
}

void DoesNotLink(const char** test) {
    // not reached
}

The error given by the linker:
test.d:(.text._Dmain+0x21): undefined reference to 
`doesNotLink(char const* const*)'

What's happening? I know there are differences in const behavior 
between D and C++, but can't figure a way around it. Any sort of 
casting trick I tried doesn't seem to help.
