It's a thing of type `check_frontend_t`, which is a function pointer
already. When you add an asterisk, you get a pointer to a function pointer.

OK, so I have narrowed down my SIGSEGV problem to having no real idea
how to do C function pointers in D code.
So I have a callback function that will be called from C library code.
It currently has signature:
