Subject: 2004-10-10 Paul Jakma <paul@dishone.st>

	* version.h.in: (pid_output*) add const qualifier.
	* command.h: Change DEFUN func to take const char *[] rather
          than char **, to begin process of fixing compile warnings in lib/.
          Nearly all other changes in this commit follow from this change.
        * buffer.{c,h}: (buffer_write) pointer-arithmetic is gccism, take
          const void * and cast an automatic const char *p to it.
          (buffer_putstr) add const
        * command.c: (zencrypt) const qualifier
          (cmd_execute_command_real) ditto
          (cmd_execute_command_strict) ditto
          (config_log_file) ditto.
          Fix leak of getcwd() returned string.
        * memory.{c,h}: Add MTYPE_DISTRIBUTE_IFNAME for struct dist ifname.
        * distribute.{c,h}: Update with const qualifier.
          (distribute_free) use MTYPE_DISTRIBUTE_IFNAME
          (distribute_lookup) Cast to char *, note that it's ok.
          (distribute_hash_alloc) use MTYPE_DISTRIBUTE_IFNAME.
          (distribute_get)  Cast to char *, note that it's ok.
        * filter.c: Update with const qualifier.
        * if.{c,h}: ditto.
        * if_rmap.{c,h}: ditto.
          (if_rmap_lookup) Cast to char *, note that it's ok.
          (if_rmap_get) ditto.
        * log.{c,h}: Update with const qualifier.
        * plist.{c,h}: ditto.
        * routemap.{c,h}: ditto.
        * smux.{c,h}: ditto. Fix some signed/unsigned comparisons.
        * sockopt.c: (getsockopt_cmsg_data) add return for error case.
        * vty.c: Update with const qualifier.
