How long can world's smallest rated chess program avoid mate?

Despite its miniscule size (under 2KB of plain C code), Micro max 4.8 (http://home.hccnet.nl/h.g.muller/umax4_8.c) plays amazingly well. Is it enough to avoid mate in 20 moves? Who will have the record for shortest win?

I'm sorry, I'm computerese illiterate. Not ashamed to fess up. The important question is : how strong is it, what's its estimated or actual elo?
