[Bug preprocessor/14460] New: --enable-c-mbchar will not work

["kutara at sayuri dot ne dot jp" <gcc-bugzilla at gcc dot gnu dot org>]

At mbchar.c, local_mbtowc() compare with a variable 'literal_codeset' to "C-
SJIS", "C-JIS" or "C-EUCJP".

The variable 'literal_codeset' is initialized at c-lex.c/init_c_lex() like this:
>  GET_ENVIRONMENT (literal_codeset, "LANG");

But proper format of the environment 'LANG' 
is "C", "ja", "ja_JP", "ja_JP.eucjp", and so on. It's depend on OS. See output 
of command "locale -a".

So the comparison at local_mbtowc() will be failed.
