What in config is C++ specific as opposed to C as far as the actual 
header file code ?

I am not concerned about the tests themselves, but rather about the 
header files. If there are C++ specific things in the header files which 
could just as easily work with C, I would like to take a look at what 
they are. if it was reasonable work, I could try to convert it as long 
as it does not affect anything in C++ negatively and was not essentially 
a "hack" to fit C++ into C.
