I found this article helpful. Since C is a "strongly typed" language it helps to review what is meant by type. In addition, like #DonaldPShimoda, I liked that the author challenged to the existing notions of type. Good read.
The author just points to selected links, without going to the links themselves. If you go to the link he points you to [1] where C typing is defined, you find that two of the three links there that claim C to be strongly typed are broken and the third link immediately qualifies the assertion with: "To be precise, relatively strongly-typed app-specific dialects of the not-very-strongly-typed language, C."
