MULTIBYTE_CHARS in c-lex.c and cp/lex.c

[Gavin Romig-Koch]

There is a undef at the top of c-lex.c that turns off MULTIBYTE_CHARS
if CROSS_COMPILE is set.  There is not a similar undef at the top
of cp/lex.c.  Can anybody shed light on why the difference?

Is it because cp/lex.c is always built with gcc, while c-lex.c might
be built with some other compiler?
