    yea its 3 on mine
    I get it after running this:

    foreach $name (split(' ', $Config{sig_name})) {
    $i++;
    printf "%3d) %s \t", $i, $name;
    if (($i % 5) == 0) { print "\n"; }
    }
    print "\n";
    1) ZERO 2) HUP 3) INT 4) QUIT 5) ILL
    6) NUM05 7) NUM06 8) NUM07 9) FPE 10) KILL
    11) NUM10 12) SEGV 13) NUM12 14) PIPE 15) ALRM
    16) TERM 17) NUM16 18) NUM17 19) NUM18 20) NUM19
    21) CHLD 22) BREAK 23) ABRT 24) STOP 25) NUM24
    26) CONT 27) CLD I tried some of the other ones, same results
      Shouldn't you start counting from 0 instead of 1 ?
