For C Programming, A Modern Approach, by K.N. King, I believe only the second edition tries to fully cover C99. I might be wrong, but I think the first edition covered C++ stuff whereas in the second edition, the author replaced the C++ stuff with more C99 stuff. For a list of differences between the first and second edition, you can visit the authors site and look at his preface. It goes in depth at the differences. I think the 2nd edition would be a better choice than the first for someone trying to learn C.
