Use a (signed) int32_t counter instead of an `unsigned int' counter
for the GPROF4 case. This allows a simpler method to be used for non-statistical profiling (it allows overhead adjustments to be subtracted from one counter without harm if that counter goes negative; otherwise the adjustment would have to be distributed). 32 bit counters were already too small for GPROF4 with a 200MHz clock. int64_t counters should be used.
