[ruby-dev:10168] [BUG] ruby-1.5.4

新井です。

NEC EWS48で、ruby-1.5.4をmakeしたところminirubyがSEGVし
ました。最後に、パッチとスタックトレースをつけます。

あと、gccのない環境で configure が失敗します。以下は、Linux 
でgccをrenameしてconfigureしたときの出力です。以下のように、
CPPFLAGS= を指定しても無視されるようです。1.4では有効だった
んですが・・・(ヨンパチでは、これやらないと一箇所コンパイル
に失敗するんですよね。むろんヨンパチが悪いんですが、)

$ CPPFLAGS='-Dconst=' ./configure
loading cache ./config.cache
checking host system type... i586-pc-linux
checking target system type... i586-pc-linux
checking build system type... i586-pc-linux
checking for gcc... gcc
checking for gcc... (cached) gcc
checking whether the C compiler (gcc  ) works... no
configure: error: installation or configuration problem: C compiler cannot create executables.
[exit:1]

# CC=cc CFLAGS='-Dconst=' ./configure すれば、大丈夫ではありますが
