gnuclient: if TMPDIR was set and connect failed, try again with /tmp
2011-06-03 Aidan Kehoe <kehoea@parhasard.net>
* gnuslib.c (connect_to_unix_server):
Retry with /tmp as a directory in which to search for Unix sockets
if an attempt to connect with some other directory failed (which
may be because gnuclient and gnuserv don't share an environment
value for TMPDIR, or because gnuserv was compiled with USE_TMPDIR
turned off).
