I am getting this when running emacs:

/usr/local/emacs/share/emacs/24.2.93/lisp/gnus/message.elc:Warning:
    `flet' is an obsolete macro (as of 24.3); use either `cl-flet' or
    `cl-letf'.

Why a user needs to care about this?

Good question.  Basically, the question is: why is this flet
macro-expanded so late (instead of during byte-compilation)?

Looks like message.el needs recompilation. I have just done that and the
warning is gone.

The problem can not be resolved by recompiling message.el. Looks more
serious.

Perhaps the warning is actually triggered by some hook or advice?  There
is no use of flet anywhere in gnus.

But message.el uses it:

(defun message-read-from-minibuffer (prompt &optional initial-contents)
  "Read from the minibuffer while providing abbrev expansion."
  ......)

Right, I was looking at trunk where it has been removed.

Unfortunately, I have no such recipe for this bug.

Seems as Andreas Schwab it is triggered by an advice I put on
message-bogus-recipient-p which has a flet.

Sorry for the noise. I have closed the bug.
