I can't reproduce this in the current trunk.
If /usr/include/sys/stat.h is present I warp to it, if not then
I just get the expected error message as shown above: Cannot find header file:
sys/stat.h.
Do you have a readable sys/stat.h somewhere in Man-header-file-path on
your system?

I'm going to take a guess that you don't in fact have a
/usr/include/sys/stat.h file on your system, because you are using a
multi-arch system where this file has moved to eg
/usr/include/x86_64-linux-gnu/sys/stat.h
I don't know how many possible architecture locations exist, but
I guess it would do no harm to add them all to Man-header-file-path,
since only one is likely to exist on most systems.

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.

Sounds about right, yes.

Yes, after 24.1,

OK. Do you want some, all, or none of the following individual users
fixing for 24.1?
Man-header-file-path
cc-search-directories
ffap-c-path
semantic-c-dependency-system-include-path
semantic-gcc-setup

I'd recommend not to touch the semantic-*.
And I wouldn't bother with cc-search-directories which doesn't even bother
to obey the prefix naming convention.
So if you can fix the remaining two, with a clear comment about the
duplication and need for unification, then that'd be wonderful,
Stefan
