GNU and Clang toolchains have useful diagnostic abilities in this direction, though no single "master switch".
For example, with -Wold-style-casts you can diganose every use of the (TYPE) EXPR casting notation, which is often seen in the lower-level C-like C++ code for punning memory.
Somewhere in some commonly included header for the project you can write declarations for C functions that should not be used, marking them deprecated. Then if people introduce strcpy or malloc or whatever you don't want, that can be diagnosed (and can fail compilation, if desired).
