* eval.c (Init_Proc): make Method and UnboundMethod independent.

They are like instance and its class. [ruby-core:00941]

* parse.y (yylex): disallow global variables like "$1ve".
  [ruby-core:00945]

* marshal.c (marshal_dump): Marshal.dump(0, false) should cause an
  error. (ruby-bugs-ja PR#421)

* regex.c (re_compile_pattern): warn if '-' is the edge of
  character range.
