[stunnel-users] stunnel-5.06 fails to build against systemd 215

Hi everyone,

We hit a bug in stunnel-5.05 and it continues in 5.06. The problem comes from systemd which moved sd_listen_fds() form libsystemd-daemon.so to libsystemd.so. However, stunnel's configure.ac still has

AC_SEARCH_LIBS([sd_listen_fds], [systemd-daemon])

For backwards compatibility, this should probably be

AC_SEARCH_LIBS([sd_listen_fds], [systemd], [], [ AC_SEARCH_LIBS([sd_listen_fds], [systemd-daemon]) ])

or similar. Please refer to our downstream bug:

Thanks.
