Here is a patch to fix the issue.

The :includes, :defines, :imports headers have been extended to accept
multiple items without parenthesis. All the following forms are now allowed:

:includes <stdio.h>
:includes <stdio.h> "strings.h" <assert>
:includes '(<stdio.h> <strings.h> <assert>)
:includes (mapcar (lambda (x) (concat "<std/" x ".h>")) '("abc" "def"
"ghi"))
(same for :imports)

:defines AA 22 BB 33
:defines "AA 22 BB 33"
:defines '("abc 123" "def 456")
:defines (mapcar (lambda (x) (concat x " " x "_def")) '("A" "BB" "CCC"))

This works either in the header as here:

#+BEGIN_SRC C++ :includes <stdio.h> "strings.h" <assert>

#+END_SRC

or in a property drawer, like that:

  :PROPERTIES:
  :includes: <stdio.h> "strings.h" <assert>
  :END:

Have fun
