GreyBear's Quake 2 Tutorials Chapter 3: Spawning Magic

Unfortunately I was unable to get this tutorial to work. I kept getting syntax errors in this error:

error C2143: syntax error : missing ')' before '*' b_check.c

in the following line of the "b_check.c" file:

//
//
void CheckItem(edict_t *ent, gitem_t *item)
//
//
