Patch fixes typo. The function's one has already been fixed by someone in extended, so the purpose is to unify the code.

#define MAX_PLAYER_COUNT (16)
The MAX_PLAYER_COUNT defined in simconst.h is also defined in simgraph16. The latter appears to work even if it is removed, but is it necessary?
Thank you! in r10248 & r10249
