tramp requires cl at runtime

emacs -Q -l tramp
M-: (featurep 'cl)   -> t

Looks like the "eval-and-compile" in tramp-compat is to blame.

When I use `eval-when-compile' instead of, I get error messages compiling
with Emacs 21, that `block', `return' and `ignore-errors' are not known.

How can I avoid this?

Best regards, Michael.

I checked out the latest tramp from tramp CVS, and changed the start
of tramp-compat to look like:

(eval-when-compile

  ;; Pacify byte-compiler.
  (require 'cl))

(eval-and-compile
  (require 'custom)

Then:

./configure --with-contrib --with-emacs=/usr/bin/emacs-21.4
make
make install

worked fine for me.

That's the trick. I didn't call configure, but "make EMACS=emacs21"
only, which returned the compiler warnings.

I'll commit the patch tonight (or you could do it, if you are faster :-)

Thanks, and best regards, Michael.
