Hi! This is the friendly automated conda-forge-linting service.

I wanted to let you know that I linted all conda-recipes in your PR (recipes/redis-plus-plus/recipe.yaml) and found some lint.

Here's what I've got...

For recipes/redis-plus-plus/recipe.yaml:

• ❌ The recipe could do with some maintainers listed in the extra/recipe-maintainers section.
• ❌ This recipe is using a compiler, which now requires adding a build dependence on ${{ stdlib("c") }} as well. Note that this rule applies to each output of the recipe using a compiler.
