* parse.y (arg): syntaxify tPOW negative number hack.

* parse.y (negate_lit): new function to negate literal numeric
  values in compile time.

* regex.c (re_match_exec): charset info may be stored in MBC
  region when $KCODE != NONE.

* error.c (set_syserr): should preserve duplicated error names.
