Hi > [PATCH] This PR enables a successful git build on z/OS. Maybe the subject could be: > [PATCH] build: support z/OS (OS/390) There’s some indirectly related things in `SubmittingPatches`: “ Describe your changes in imperative mood, e.g. "make xyzzy do frotz" instead of "[This patch] makes xyzzy do frotz" or "[I] changed xyzzy to do frotz", as if you are giving orders to the codebase to change its behavior. Try to make sure your explanation can be understood without external resources. Instead of giving a URL to a mailing list archive, summarize the relevant points of the discussion. >From which I infer that “This PR” is considered redundant. As for the `build:` prefix: many different prefixes have been used for this file (`git log --no-merges -- config.mak.uname`). -- Kristoffer Haugsbakk
