Basically with -std=c11 fork/exec* are not known identifiers (because they are not part of the C11 standard). Maybe this can be what it says: Also fork (when not in strict standards language mode e.g. -std=c90 or -std=c++98) calls are detected and correctly handled (double counting will not happen).
