I don't know of a reference, but C encourages to do more things at run time, whereas C++ encourages you to do more things at compile time. Simplest example of this is probably qsort() vs. std::sort(), but it extends far beyond this. So you end up with slightly slower code in C, but much faster compile times, and much smaller binaries. So if you want smaller binaries or faster compile times, you'll have an easier time keeping them in C. Of course you'll have an easier time keeping & introducing more bugs in C too, but that's another matter.
