All C compilers are actually required to allow you to pass a size like 
that.  It doesn't have any effect whatsoever, though.  Any number you 
put between those [] is really just decoration.  These 4 function 
declarations are totally equivalent:

	void p(char x[256]);
	void p(char x[7]);
	void p(char x[]);
	void p(char *x);
