Yes, I was too lazy to restore all the sources from all languages cause I tested them within huge time difference ^^
Can only bring C sources I compiled yesterday and PB you can compile yourself.
C anyway has no concurents exept ASM maybe - the executable it generated is almost completely filled with 0x0 (unlike PB), so actual size is much lesser and easily can be trimmed to 268 bytes using some external PE editor (268 is the minimal exe size Windows7 is abble to run).
PS. That is not related to topic directly, the windows program which takes only 314 bytes:
