"At present, there is no C or C++ syntax for import declarations. 
Clang will track the modules proposal in the C++ committee. See 
the section Includes as imports to see how modules get imported 
today."

So Object-C can import C, but *C* cannot import *C*.

Walter added __import support in *.c, clang could have done the 
same but they *didn't*, they were also probably just 10 lines 
away from the goal.
