In test builds of spack-stack with gcc@14 (see JCSDA/spack-stack#1908) it was found this package needed extra flags to build.

Thanks, make sense. I assume this is compiler warnings being upgraded to errors; we have made a bit of progress recently on cleaning up some warnings, but I don't know if all the relevant ones are gone.

@takluyver Yes. I was building with gcc@14 and it looks like things that used to be warnings are now errors. This just moves those back to warnings.
