I agree. The only flag that I was missing in this project in fact was VTIME. It seems to be part of non-canonical mode, like VSTART, VSTOP, etc. What do you think? Should this PR include only VTIME?

There's an ongoing discussion about the status of libc bindings in stdlib (#13504). The general idea is that we don't plan to support any bindings that are not used in stdlib itself. Unused bindings might be removed in the future (#11955). So I don't think it's a good idea to add more unused bindings at this point. This discussion is not finialized and might come to a different conclusion after all (though I doubt it).

If you need specific bindings for your project, it's probably best to define them in your own code.

(I really should just restart my posix shard as a libc shard, with libvirt VMs to autogenerate the bindings for all supported targets)

Closing. We shouldn't add new unused libc bindings to stdlib until there's a decision that we definitely want to maintain them.

Collecting such bindings in a shard seems like a good idea.
