[dovecot-cvs] dovecot/src/lib failures.c,1.27,1.27.2.1

[cras at dovecot.org]

Update of /var/lib/cvs/dovecot/src/lib
In directory talvi:/tmp/cvs-serv12782

Modified Files:
      Tag: branch_1_0
	failures.c 
Log Message:
If writing to log file fails, restore errno before %m is used. Although the
log writing most likely fails anyway at that point, but at least strace logs
show it right. :)
