Zsh だと Darwin で gdb が動かない。こんな感じ:
pineapple% gdb Unable to start GDB: unknown architecture "unknown-apple-darwin5.4"
でも XEmacs から M-x shell して実行した shell (tcsh) だと、こんな感じにきちんと動く。
pineapple: {152} gdb

なぜだか よぉ分からんが、まぁいいかぁ。ただ、opensource.apple.com の Bug entry にuname() should include processor typeというエントリがあるんだけど、これも関係あるのかなぁ。
