Subject: [ruby-dev:41219] [ruby_1_9_2] コンパイルエラー

ruby_1_9_2ブランチのコンパイルでエラーが起きます。

Stop.

単純なコードの追加ミスと思います。

ところで、この A とか F といったマクロですが、

% egrep 'define[ \t]A[ \t]' enc/*
enc/big5.c:#define A ACCEPT
enc/emacs_mule.c:#define A ACCEPT
enc/euc_jp.c:#define A ACCEPT
enc/euc_kr.c:#define A ACCEPT
enc/euc_tw.c:#define A ACCEPT
enc/gb18030.c:#define A ACCEPT
enc/gbk.c:#define A ACCEPT
enc/shift_jis.c:#define A ACCEPT
enc/utf_8.c:#define A ACCEPT

と、同じものが copy & paste されたように散在しています。何かまとめた
方が良いのではないでしょうか、今回のような誤りを防ぐ意味でも。
