Issues with newer glibc (strlcpy related) and warnings in date handling in headers.c #21
Description
In Debian downstream was reported the following:
https://bugs.debian.org/1068782
which will cause libesmtp and reverse depending packages to be removed, being a
release critical bug. Michael Hudson-Doyle reported the following:
Package: libesmtp
Severity: normal

Dear Maintainer,
Apologies for submitting this as only one report. libesmtp was failing
on Ubuntu on armhf only because although strlcpy is now in glibc, the
declaration is only found if _DEFAULT_SOURCE or _BSD_SOURCE is defined.
While looking at this I saw some scary warnings about the date handling
in headers.c which I fixed the easy bits of.
In Ubuntu, the attached patch was applied to achieve the following:
* d/patches/time64: cast time_t values to long long before passing to
*printf functions (code storing time_t values in void* variables will
still break in 2038).
* d/patches/default-source: define _DEFAULT_SOURCE to get access to
prototype of strlcpy.
Thanks for considering the patch.
Cheers,
mwh
