ignore external cast-function-type warnings

When building on Ubuntu 22.04 (gcc 11.3) with OpenMPI I am getting the
following warnings:
```

The code in question doesn't look correct, but we are not using the c++

In the beginning the Universe was created. This has made a lot of people very angry and has been widely regarded as a bad move.
