DHi Simon, It seems that GHC is "helpfully" adding flags to your invocation see https://ghc.gitlab.haskell.org/ghc/doc/users_guide/packages.html#package-environments
You can see exactly what is being added by inspecting the environment file /home/simonpj/.ghc/x86_64-linux-9.5.20220628/environments/default. You can safely delete .ghc/x86_64-linux-9.5.20220628/environments/default. Although without knowing how it got there, it may re-appear. You can set `export GHC_ENVIRONMENT=-` or pass `-package-env -` on your command line to disable the reading of environment files.
