Help!  This function came with the tetris game I got for Unix based
machines.  The problem is vsprintf is undefined using my C libraries.

Does anyone have a simple solution?  Please post the answer because
others have had the same problem.  Thanks in advance.

|*  This is my home-made varargs-based version of C++'s neat function of   *|
|*  the same name.  It saves all that tedious mucking about with static	   *|
|*  buffers which you sprintf into, then forget all about, by basically	   *|
|*  being a sprintf with its own statis storage.  It takes as arguments	   *|

/*VARARGS*/
char *form (va_alist)
  va_dcl
{
  va_list pvar;
  char *fmt_string;
  static char result[LINELEN];
  
  va_start (pvar);
  fmt_string = va_arg (pvar, char*);
  (void) vsprintf (result, fmt_string, pvar);
  va_end (pvar);
  return (result);
}
