windows git配置

报错一

## 报错代码：
#1.情况1
unable to execute file code740

#2.情况2
This problem is probably due to using incompatible versions of the cygwin DLL.
Search for cygwin1.dll using the Windows Start->Find/Search facility
and delete all but the most recent version.  The most recent version *should*
reside in x:\cygwin\bin, where 'x' is the drive on which you have
installed the cygwin distribution.  Rebooting is also suggested if you
are unable to find another cygwin DLL.

## 解决办法
以上2种情况通过重装git解决：win64系统下载32为git，即可解决

报错二
