Someone else posted an incomplete followup that is likely to provoke all
sorts of noise.  The declaration in init_board here is incorrect; it
must be one of:

	int (*Board)[3];	/* I recommend this over all others. */

or:

	int Board[][3];

or:

	int Board[3][3];

You may get away with

	int Board[99][3];

or other bogus values in the first dimension, but I would advise against
it even if ANSI X3.159-1989 permits it (I do not know whether it does).

I recommend the first format because it is the least misleading.

See the Frequently Asked Questions for discussion as to why the first
declaration is correct.
