Date: Fri, 17 Sep 2010 07:13:51 -0700

Actually, this Tramp bug prevents me from being able to use Emacs at all - the
error pops up all of the time.

emacs -Q
 
In *scratch*, call file-remote-p with a remote file name (can be a fictitious
file):
 
(file-remote-p "/foo-2.foo.com:/usr/share/emacs/21.3/lisp/README")
 
You get this error:
 
 "Symbol's function definition is void: tramp-compat-call-process)"
 
Note: For some reason "SimonTatham" seems to be hard-coded here. Never heard of
him.

Under GNU/Linux, it is not reproducible. I will try to hijack a Windows
machine, in order to reproduce.

In the meantime, does it help to evaluate first (require 'tramp) in the
scratch buffer?

He's the author of PuTTY. He uses his (own) name for storing values in
the Windows registry.

emacs -Q

M-x load-library tramp

gives the same error.  Likewise evalling (require 'tramp).

And I cannot reproduce this on today's build on Windows.  It works
okay for me.

Since Drew uses precompiled binaries from a few days ago, I'm guessing
that this is due to the problems with Tramp loaddefs, which was fixed
by Juanma.  Or maybe some other similar problem.

Drew, do you see in lisp/ChangeLog this entry:

  2010-09-13  Juanma Barranquero  <lekktu <at> gmail.com>

	  Port tramp-related Makefile changes of revnos 101381, 101422 to Windows.

	  (TRAMP_SRC): New macro.

Nope. This is all I see for that date:

2010-09-13  Daiki Ueno  <ueno <at> unixuser.org>

	* epa-file.el (epa-file-insert-file-contents): If visiting, bind
	buffer-file-name to avoid file-locking.  (Bug#7026)

2010-09-13  Julien Danjou  <julien <at> danjou.info>

	* notifications.el (notifications-notify): Add support for
	image-path and sound-name.
	(notifications-specification-version): Add this variable.

So you're probably right.  Feel free to close the bug, if that's the case.

I prefer to wait until you have a later binary and can verify that the
bug is gone.  With the plethora of methods used by Tramp, you can
never know: maybe the bug is in some method that isn't run on my
machine (although I did try using the `plink' method directly as well).
