* Recently the prototypes for the application hook functions were moved out of the kernel .c files and into the .h files. That changes results in compile time warnings for projects that provide hook functions with a slightly different prototype - in particular where signed char * is used in place of just char * as an older FreeRTOS coding convention required chars to be explicitly qualified as signed or unsigned. This checkin fixes the warnings by ensuring the signature of implemented hook functions matches the signature of the prototypes.
