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).

| 617 | 25 /* Separation into WINDOW_SLOT / WINDOW_SAVED_SLOT by Ben Wing, June 2001. |
| 26 | |
| 27 NOTE: No semicolons after slot declarations in this file! The | |
| 28 definitions of WINDOW_SLOT (and possibly WINDOW_SAVED_SLOT) need | |
| 844 | 29 to include a semicolon. This is because these may be defined as |
| 30 nothing, and some compilers don't tolerate extra semicolons in | |
| 31 structure definitions. | |
| 617 | 32 |
| 33 WINDOW_SLOT declares a Lisp_Object that is not copied into the | |
| 34 saved_window struct of a window configuration, or is handled in | |
| 35 a special way in window configurations. | |
| 36 WINDOW_SLOT_ARRAY is the same for an array of Lisp_Objects. | |
| 37 WINDOW_SAVED_SLOT declares a Lisp_Object that is copied with no | |
| 38 special handling into the saved_window struct of a window | |
| 39 configuration. You must also declare the comparison function, | |
| 40 either EQ or EQUAL_WRAPPED (i.e. Feq() or Fequal()). | |
| 41 WINDOW_SAVED_SLOT_ARRAY is the same for an array of Lisp_Objects. | |
| 42 | |
| 1204 | 43 Callers should define WINDOW_SLOT (with a terminating semicolon if not |
| 44 blank), and WINDOW_SAVED_SLOT if different; otherwise the latter will be | |
| 45 defined using WINDOW_SLOT. Callers should also either (a) do nothing | |
| 46 else (which defines WINDOW_SLOT_ARRAY using a for() loop, appropriate | |
| 47 for normal code), define WINDOW_SLOT_DECLARATION (which defines | |
| 48 WINDOW_SLOT_ARRAY using WINDOW_SLOT (slot[size]), appropriate for a | |
| 49 struct definition), or define WINDOW_SLOT_ARRAY themselves. In the | |
| 50 first two cases, WINDOW_SAVED_SLOT_ARRAY will be defined in the same | |
| 51 fashion, using WINDOW_SAVED_SLOT. In the last case, if | |
| 52 WINDOW_SAVED_SLOT is defined, the caller must provide an appropriate | |
| 53 definition of WINDOW_SAVED_SLOT_ARRAY; otherwise, it will be defined | |
| 54 using WINDOW_SLOT_ARRAY. | |
| 617 | 55 |
| 56 Callers do not need to undefine these definitions; it is done | |
| 57 automatically. | |
