[pbc_to_exe]: * On my platform at least (32-bit Ubuntu Gutsy), repeated string   concatenations are much faster than pushing to an array and   doing a subsequent join.  With this patch, "pbc_to_exe perl6.pbc"   takes 5.5 seconds on my system instead of 18. * We also eliminate the sprintf "%d" step, since $S0 = $I0 will   have the same effect.
