Rubyでは不要なKR_headersやCONSTなんかも削っちゃおうかなあ。

こんな感じでしょうか。

・#define KR_headers を削除
・#ifdef KR_headers で囲まれていた部分を削除して整形
・CONST → const と置換して、#define CONST を削除

gcc のソースを確認したところ、Mac OS X でしか BIG_ENDIAN を
define してくれないようなので、CPU ごとのエンディアン判定を
ã‚ã‹ã‚‹ç¯„å›²ã§è¿½åŠ ã—ã¾ã—ãŸã€‚

また、Win32 環境の判定がコンパイラ限定でうまくないので、型判定に
統合しました。
