* 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) git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@4050 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
