[ruby-dev:25408] Re: 1.9.0でbcc版がコンパイルできない

山本です。

では、とりあえずそうしておきます。

ところで、色々試すうちに、下のようにして64bit整数のない環境にすると、
test/digest/test_digest.rb が正しく実行されないことに気づきました。

これは digest/sha2 がコンパイルされないためですが、
digest/md5 や digest/sha1 などはコンパイルされるので、digest/sha2 用のテストだけ
スキップすべきだと思います。

また、新しいテスト test/ruby/test_rand.rb も 64bit整数のない環境で失敗するようです。
