I can't find conclusive examples for is- ctype routines, but here is how tolower was defined during the first few releases of OpenBSD, as forked from NetBSD:
#define tolower(c) ((_tolower_tab_ + 1)[c])
It's still defined similarly on NetBSD, today: http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/sys/ctype_inl...
Also, EOF is a permitted value and typically -1 (thus the +1 in the above), though that would typically only be an issue for non-C locales.
