I would also prefer to get rid of that parameter, but changing the other sysdeps might be a bit messy.

is that code copied from musl?

ABI checker complains since we changed `setpgrp` to take no arguments, but it was wrong before so I'm not sure that's an issue.

This needs to be rebased to pass CI.

Instead of writing our own regex implementation, we could port an existing one such as https://github.com/kokke/tiny-regex-c or musl's

This needs the 'affects ABI' label.

libsmarter's make_shared at least seems to call `operator new`.

Ah, okay. `allocate_shared` should do the same thing as `make_shared` but take an explicit allocator. We can just use that, then.

I believe this is covered by #530 and #253.

Is this still an issue?
