* signal.c (sighandle): should not re-register sighandler if

  POSIX_SIGNAL is defined.

* eval.c (error_print): errat array may be empty.

* parse.y (yylex): float '1_.0' should not be allowed.

* variable.c (var_getter): should care about var as Qfalse
  (ruby-bugs#PR199).

* array.c (cmpint): <=> or block for {min,max} may return bignum.

* array.c (sort_1): use rb_compint.

* array.c (sort_2): ditto.

* enum.c (min_ii): ditto.

* enum.c (min_ii): ditto.

* enum.c (max_i): ditto.

* enum.c (max_ii): ditto.

* mkconfig.rb: use String#dump to generate Ruby string literal.

* range.c (range_eql): should override 'eql?'
