* eval.c (rb_load): put rb_load_file() in a thread critical
section. [ruby-dev:20490]
* eval.c (compile): put rb_compile_string() in a thread critical
section.
* variable.c (rb_const_get_0): should not warn if constant is not
defined. (ruby-bugs-ja PR#509)
* bignum.c (rb_big2dbl): give a warning on overflow.
(ruby-bugs-ja PR#510)
* util.c (ruby_strtod): change MDMAXEXPT from 511 to 308.
* pack.c (utf8_to_uv): long is sufficient. LONG_LONG is not
required.
* bignum.c (rb_big2str): support 32 bit (without `long long' type)
machines. (ruby-bugs-ja PR#512)
