Ok, I compiled it on both AIX and Ultrix... Here are changes which I needed
in order to compile it:

On AIX:
In Makefile:
   Changed CFLAGS to: CFLAGS = $(OPT) -DAIX
   Changed LDLIBS to: LDLIBS = -lcurses
In tt.c:
   Changed:
     #ifdef SYSV
     extern int sprintf ();
     #else /*SYSV*/
     extern char *sprintf ();
     #endif /*SYSV*/
   To:
     #ifndef AIX
     #ifdef SYSV
     extern int sprintf ();
     #else /*SYSV*/
     extern char *sprintf ();
     #endif /*SYSV*/
     #endif /* AIX */

On Ultrix:
There is no usleep function, so I needed to add one.
In Makefile:
   Changed SRC to: SRC = tt.c utils.c screen.c pieces.c game.c usleep.c

I grabbed usleep.c from xpilot source ;-)
So here it is:

usleep.c:
------------------------ 8< Cut here 8< ----------------------
/*
#ifndef lint
static char sccsid[] = "@(#)usleep.c	1.3 91/05/24 XLOCK";
#endif
*/
/*-
 * usleep.c - OS dependant implementation of usleep().
 *
 * Copyright (c) 1991 by Patrick J. Naughton.

 */

#include <sys/types.h>
#include <sys/time.h>


#ifndef	lint
static char sourceid[] =
    "@(#)$Id: Porting,v 1.1.1.1 2003/05/27 10:46:19 mike Exp $";
#endif


void usleep(unsigned long usec)
{
#if 0 /* SYSV */
    poll((struct poll *) 0, (size_t) 0, usec / 1000);	/* ms RES */
#endif
    struct timeval timeout;
    timeout.tv_usec = usec % (unsigned long) 1000000;
    timeout.tv_sec = usec / (unsigned long) 1000000;
    (void) select(0, (void *) 0, (void *) 0, (void *) 0, &timeout);
}
