I forget what they were, but ISTR seeing one or two missing functions
in one of the headers I worked on.

What I'd had in mind was to have _BSD_SOURCE ready "before 0.9.0" (when
you were talking about having the license change).
I haven't made much progress on it lately, and have been going through
header by header (there are no patches I haven't sent left).  If anyone
wants to work on the other headers, they're welcome to do so.  A header
should take less than 3 hours to go over, from my experience.

You're welcome, and thank you for developing musl!
