That isn't clear to me and that's at least partly because C & Unix
standards themselves are a complete mess. The fact that they are often
paywalled doesn't help. 

This complete mess is why The Open Group and IEEE pulled together the
Single Unix Specification and have published it as an IEEE Standard.
Wikipedia seems to say that the Single Unix Specification and POSIX are
"technically identical". 

I seem to recall someone saying a long time ago that the basic
requirement for building NetBSD is POSIX.

I checked
https://sourceware.org/git/?p=glibc.git;a=blame;f=time/time.h;h=b6b439a45273ff4440372a42cde8cb7b4c87b194;hb=HEAD
and the strptime change was made to GNU libc in 2016. I'm going to
guess that recent compiler changes have tripped up a fix we had in
place to make this work. While searching the web I found references to
Linux people having this same problem when changing which standard of C
they were asking GCC to compile. This is a somewhat fluid area right
now. 

I'm checking out NetBSD on my Ubuntu box to see if I can gather any
more information.
