Bug #4397: test-mkmf fails due to compilation errors
http://redmine.ruby-lang.org/issues/show/4397

起票者: Shyouhei U.
ステータス: Open, 優先度: Normal
ruby -v: ruby 1.9.3dev (2011-01-21) [x86_64-linux]

手元の環境では r30621 から以下のようにtest-allが失敗するようになっています。

ちょっと変更の意図が分からないので説明していただけませんか。困っているので、特に意味が無いようであればrevertします。

あと以前から思っているのですが、ユーザーから渡されたコンパイルフラグを勝手に弄るのは感心しません。
