I know nothing, but in _my_ <term.h>, tparm() normally has ten
arguments, not three.  If this is very old code, then defining
__10_10_COMPAT_CODE might help.

   "/usr/include/term.h":

[...]
#ifdef __10_10_COMPAT_CODE
/*
 * The old tparm() API prototype is present only for backward compatibility.
 * It wil not be available in future releases.
 */
extern	char	*tparm __((char *, ...));
#else
extern	char	*tparm __((char *, long, long, long, long, \
		       long,   long, long, long, long));
#endif /* __10_10_COMPAT_CODE */
[...]

(But modernizing the code might be a better idea.)
