I had some concerns about providing *_r variants of these that match names from glibc but aren't compatible, but I see the ultimate plan is that these aren't intended to be exported from libc at all- this seems OK.

Hm, I didn't realize glibc had these routines. They picked different argument orderings and state struct name (and field names), but otherwise look pretty similar. Yeah, I didn't intend to export these routines from libc and don't see a great reason to.
