There are a few reasons for this.
1. Using GCC with certain selected optimizations reduces to compiled code size considerably. e.g high optimization (-O3) is actually worst than medium (-O2, it produces a lot of excessive in-line stuff.
2. Other compilers can add a lot of bloat to the executable file, Microsoft, Intel etc.
3. I compress the file after compilation with an executable packer which halves it's size, (in this case from 400kb to 200kb)
4. I'm just a cool compiler I guess!

I finished the 60 game match between crafty19.13 v crafty19.18. The gap closed a bit: crafty 19.13: 20 wins, 15 losses, 25 draws, 54.17%.
I used the DC version for 19.13, and the PS sse version for 19.18. On my machine, for 19.18, the PS sse version has a 10% higher nps rate (1,209,520 v 1,079438nps) than the DC version. So I assume that if I had the PS sse version for 19.13, the results would have been even better for 19.13.
