Subject: 24.3.90; invoking c-mode always loads `cl'
Date: Sun, 11 May 2014 22:49:25 +0900

c-mode loads `cc-langs' and it always, as it is execution time, loads `cl'.
I suspect in cc-langs

    (cc-external-require 'cl)

sholud be simply changed to

    (eval-when-compile 'cl)

as in cc-defs.

It would be great if we were allowed to replace cc-bytecomp more
generally with standard syntax, as proposed in
http://debbugs.gnu.org/14496

Anyway, I don't think that's the real cause.

emacs -Q -f c-mode

is not supposed to load cc-langs, yet it does since 24.3.

I don't know well the real cause, at least in my environments (MingW
24.3, Cygwin 24.4),

(list (featurep 'cl) (featurep 'cc-langs))

return (t t) after "emacs -Q -f c-mode".

I think I bisected this to somewhere around r108513 on the current
emacs-24 branch. These are changes related to macro expansion.

108512 is ok  (emacs -Q -f c-mode does not load cc-langs)
108513 fails to build
108514 build infloops?
108515 build infloops?
108516 emacs -Q -f c-mode loads cc-langs

cc-mode tries to do different things in compiled code and uncompiled
code (yay; eg c-make-init-lang-vars-fun, which is what I think is
loading cc-langs). Perhaps we are getting the wrong version.

The only things cc-langs uses from cl are delete-duplicates (perhaps
delete-dups would do) and mapcan (perhaps apply+mapcar would do).
I simply replaced them by their cl- versions.

Figuring out why cc-langs is loaded at runtime is beyond me.
I'll leave this aspect open as a cc-mode bug of normal priority.
