This patch has no effect on runtime. The sig_map[] array has MAXMAPPED_SIG (35) members so my static checker complains that the <= should be <. But in this case it's not possible for "sig" to be more than 31 because of the "else if (sig >= SIGRTMIN)" condition since SIGRTMIN is 32. The last three elements, 32-34, of sig_map[] are empty so this code works as designed.
