我可以在Windows上运行Emacs M-x ediff而不安装Cygwin吗？
问题描述：
是否有必要安装Cygwin（包括diff）或MinGW（大概也可以这样做），以确定foobar.txt和foobar.txt之间的差异。
Is it necessary to install Cygwin (which includes diff) or MinGW (which presumably also does) for something as simple as determining the differences between foobar.txt and foobar.txt~?
答
你不需要那么久，因为你有一个diff.exe程序，如GNUWin32 diff-utils版本，在你的PATH。 Emacs本身不包括执行差异的机制。
You don't need those long as you have a diff.exe program, such as the GNUWin32 diff-utils version, in your PATH. Emacs itself doesn't include the mechanics for performing the diffs.
