Bug: org-babel tries to execute raw output of C code

[William Everett <will@spings.net>]

Emacs apparently tries to execute the output of the following source 
code block

#+BEGIN_SRC C :results raw
printf("(foo)");
#+END_SRC

When I run this code via C-c C-c I get this error in my *Messages* buffer:
eval: Symbol's function definition is void: foo

If I change the :results to something else like table, I get the 
expected RESULTS block. If I remove the parentheses inside the quotes, I 
get the expected raw results.
