The one in c-lex.c should probably be removed. The rationale for it being
there is that the compiler can only recognize and convert multibyte
characters using information provided by the host locale, which may not
make any sense for the target when cross compiling. However, we have
support for several pseudo-locales (C-JIS, C-SJIS, C-EUCJP) which could
be useful in a cross compiler and other host-locale character sets may
also be valid on the target of a cross compiler. So I say, leave it
enabled for cross compilers as well.
