There seems to be a ridiculous number of possibilities:
http://wiki.debian.org/Multiarch/Tuples
I suggest something like this instead:
(defcustom Man-header-file-path
(let ((arch (with-temp-buffer
(when (eq 0 (ignore-errors
(call-process "gcc" nil '(t nil) nil
"-print-multiarch")))
(goto-char (point-min))
(buffer-substring (point) (line-end-position)))))
(base '("/usr/include" "/usr/local/include")))
(if (zerop (length arch))
base
(append base (list (expand-file-name arch "/usr/include")))))
"C Header file search path used in Man."
:type '(repeat string)
:version "24.1" ; add multiarch
:group 'man)
There seem to be a few other places in Emacs that use usr/include (eg
ffap-c-path), so perhaps this should be centralized somewhere.
