Yeah, when I used it, I just used an absolute path. It's not entirely 
intuitive.

Would it be reasonable to automatically add the value of 
(file-name-directory buffer-file-name) to GCC's search path when (1) 
non-system imports are used and (2) buffer-file-name is non-nil? If we 
do, then any header in the same directory as the *.org file should "just 
work".

Seems like it would be safe, and I'm happy to try putting that together 
if there's interest.
