Hi, Emacs,
In this macro declaration:
(defmacro c-declare-lang-variables ()
`(progn
,@(mapcan (lambda (init)
`(,(if (elt init 2)
`(defvar ,(car init) nil ,(elt init 2))
`(defvar ,(car init) nil))
(make-variable-buffer-local ',(car init))))
(cdr c-lang-variable-inits))))
, (from cc-engine.el), the byte-compiler gives this warning:
"Function `mapcan' from cl package called at runtime".
It is clear that the mapcan, being within a ,@ construct, does its work
at macro-expansion time, i.e. compile time.
Thus the warning message is wrong. This is a bug.
