* lib-src/emacsclient.c: Disable -Wformat-truncation=2, to avoid false alarms about the new snprintf calls. (local_sockname): New function. (set_local_socket): Use it. Prefer XDG_RUNTIME_DIR (if set) for location of socket directory. Avoid unnecessary memory allocation by using snprintf to destination. * lisp/server.el (server-socket-dir): Prefer XDG_RUNTIME_DIR if set.
This directory contains the source code for the architecture-dependent
files that go in ${archlibdir}. At present, these are mostly utility
programs used by GNU Emacs.
