It should be stated as a rule that a C file should never include types/xxx.h when proto/xxx.h exists, as it gives less exposure to declaration conflicts (one of which was caught and fixed here) and it complicates the file headers for nothing. Only types/global.h, types/capture.h and types/polling.h have been found to be valid includes from C files.
