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).

| 0 | 1 This directory contains C header files containing |
| 2 operating-system-specific definitions. Each file describes a | |
| 3 particular operating system. The emacs configuration script edits | |
| 4 ../config.h to include the appropriate one of these files, and then | |
| 5 each emacs source file includes config.h. | |

| 7 General XEmacs Changes | |
| 8 --------------------------- | |
| 9 The following is a list of those changes made globally across all | |
| 10 files. They are not marked individually in each header file. All | |
| 11 other changes should be preceded by a comment /* XEmacs change */. | |
| 12 | |
| 13 | |
| 14 1. Removed all #defines of [read|write|open|close]. This is now | |
| 15 handled automatically by checking the INTERRUPTIBLE_IO etc. flags. | |
| 16 | |
| 17 2. Removed all instances of #undef SIGIO and replaced them with | |
| 18 #define BROKEN_SIGIO. Jamie says: | |
| 19 | |
| 20 /* use BROKEN_SIGIO instead of this kludge -- jwz */ | |
| 21 | |
| 22 3. All instances of HAVE_GETWD, HAVE_DUP2, HAVE_UNISTD_H, NEED_UNISTD_H, | |
| 23 HAVE_GETTIMEOFDAY and NEED_REALPATH removed. We detect these | |
| 24 automatically with configure. | |
| 25 | |
| 26 4. All instances of HAVE_X11 replaced with HAVE_X_WINDOWS. We don't | |
| 27 support X10 or earlier so the HAVE_X11 define was purged. | |
| 28 | |
| 29 5. Most of the signal crap (e.g. redefining sigsetmask, defining | |
| 30 POSIX_SIGNALS) has been removed. There are four possible | |
| 31 signal paradigms that all systems fall into, and we auto-detect | |
| 32 them in configure and handle them in syssignal.h. | |
| 33 | |
| 34 6. Removed references to INTERRUPT_INPUT. XEmacs does not use | |
| 35 this bizarre way of reading input. | |
| 36 | |
| 37 7. Removed references to BROKEN_FIONREAD. FIONREAD is used only | |
| 38 in INTERRUPT_INPUT and in the select() emulator, neither of | |
| 39 which are supported in XEmacs. | |
| 40 | |
| 41 8. Removed references to NOMULTIPLEJOBS. This is unused in XEmacs | |
| 42 and in FSF Emacs. | |
| 43 | |
| 44 9. Removed references to HAVE_WAIT_HEADER and WAIT_USE_INT. | |
| 45 They are unnecessary with the cleaned up syswait.h in XEmacs. | |
| 46 (We autodetect sys/wait.h). Instead, #define or #undef | |
| 47 HAVE_UNION_WAIT. | |
| 48 | |
| 49 10. Removed BSTRING. Not used anywhere. (If the header file | |
| 50 says there are bugs in bcopy() or the like, however, a | |
| 51 #define BROKEN_BCOPY is added for reference.) | |
| 52 | |
| 53 11. Removed #defines of bcopy, bzero, bcmp, index, rindex. | |
| 54 XEmacs makes consistent use of the ANSI-equivalent | |
| 55 functions memcpy, memset, memcmp, strchr, strrchr. | |
| 56 | |
| 57 12. '#define subprocesses' removed. Use '#define NO_SUBPROCESSES' | |
| 58 if they don't exist. | |
| 59 | |
| 60 13. References to HAVE_VFORK removed. configure detects this. | |
| 61 | |
| 62 14. Removed references to SYSV_SYSTEM_DIR, NONSYSTEM_DIR_LIBRARY, | |
| 63 HAVE_SOCKETS, HAVE_SYSVIPC. configure detects these. | |
| 64 | |
