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

[kutara at sayuri dot ne dot jp]

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.

I think this is all fixed in 3.4.0, can you try a snapshot of 3.4.0?

3.4.0 has substantial improvements, but I do not know yet whether it works for
real-world Japanese locales.  If you can test it that would be much appreciated.
