Are these C++ exceptions safe?

[David Banas]

In getting the new Enable 6.0.0 successfully built under conda on my M2 MacBook, I needed to add two new C++ error exceptions. I now have this in the build: section of my meta.yaml file:

  script_env:
    - CFLAGS=-Wno-c++11-narrowing -Wno-register -Wno-incompatible-function-pointer-types

And I'm wondering: are these all safe?

Thanks,
