(defun hmw/org-prop-append(prop value)
(save-excursion
(org-up-heading-safe)
(format "%s %s" value (cdr (assq prop
(car (org-babel-params-from-properties)))))))
(defalias 'A 'hmw/org-prop-append)
I use it like this:
* foo
:PROPERTIES:
:header-args: :flags -Wall
:END:
** bar
#+begin_src C :flags (A :flags "-lm")
#+end_src
** baz
:PROPERTIES:
:header-args: :flags (A :flags "-lcunit")
:END:
#+begin_src C
#+end_src
