I highly recommend "21st Century C" (http://shop.oreilly.com/product/0636920025108.do) as a tour of modern C programming, including use of C99 features. It goes over C tooling (profiling, debugging, testing, cross-platform deployment), and explores C99.

There's a newer edition available which has been published recently:

Following your recommendation, to people interested in learning about Modern C++, Stroustrup's Tour of C++ is a recommended read.
