Your mailer is breaking up threads, which is making it very annoying to
follow where your replies are landing.

strftime() has been formatting %s since Oct 2015 (if you can call that
"lately").  In fact, you made me check git history: it was not me that
added it (like I thought, so I must have added it in gnulib instead);
but Brian - in fact, the same Brian who is now working on adding %s to
strptime().

The point remains: if you want your program to be portable, you should
not use %s.  But if your program is okay with demanding a GNU/Linux
environment rather than sticking to portable code, then Cygwin still
tries to cater to that by providing as many GNU/Linux extensions as
possible, and pointing out where we fall short is appreciated.  But
still, someone has to code it, this is a volunteer effort, and we tend
to scratch our own itches.  The fact that strptime() lagged strftime()
by nearly 2 years in adding %s support is par for the course.  It's not
worth complaining about, and if you want faster action, then submit
patches yourself instead of asking others to do it for you.
