I uploaded a snapshot containing the fixes in tzload and strftime to
https://cygwin.com/snapshots/  Please give it a try.

======================


I didn't try the snapshot, but I did try email.

Now, running setup (with no-admin) gives a postinstall script error. Sending a couple test emails worked, but there seems to be an invalid assumption, that the user will have admin, in the postinstall script, giving:


Package: _/Unknown package
email.sh exit code 1


/var/log/setup.log.full excerpt:

Excerpt from /etc/postinstall/email.sh where error happens:


SYSTEMUID=$(sed -ne '/^[^:]*:[^:]*:[0-9]*:[0-9]*:[^:]*,S-1-5-18:.*:/{s/[^:]*:[^:]*:\([0-9]*\):.*$/\1/p;q}' /etc/passwd)
ADMINSGID=$(sed -ne '/^[^:]*:S-1-5-32-544:.*:/{s/[^:]*:[^:]*:\([0-9]*\):.*$/\1/p;q}' /etc/group)
setfacl -m u::rw-,g::rw-,o:r-- /etc/defaults/etc/email/*
if [ -n "${SYSTEMUID}" -a -n "${ADMINSGID}" ]
then
chown "${SYSTEMUID}:${ADMINSGID}" /etc/defaults/etc/email/*
else
...


This is using cygwin  1.7.34-003   x86_64.

A: Somewhat. :)
