branch: emacs-24
commit 6ec5ee8872bfb8b0ebc53d98fcb8f284e08c147f
Author: Michael Albinus <address@hidden>
Date: Thu Nov 20 20:10:15 2014 +0100
Improve XEmacs compatibility.
* net/tramp.el (tramp-autoload-file-name-handler):
Wrap `temporary-file-directory' by `symbol-value', it doesn't exist in
XEmacs.
(tramp-read-passwd): Don't use `with-timeout-suspend' and
`with-timeout-unsuspend' if they don't exist, like in XEmacs.
(tramp-time-less-p, tramp-time-subtract): Remove functions.
(tramp-handle-file-newer-than-file-p, tramp-time-diff):
* net/ttramp-adb.el (tramp-adb-ls-output-time-less-p):
* net/ttramp-cache.el (tramp-get-file-property):
* net/ttramp-smb.el (tramp-smb-handle-insert-directory):
Use `time-less-p' and `time-subtract, respectively.
