I suggest to not use the xargs style. Currently, I almost cannot find a good "find.exe" and "xrags.exe" to work well together.

What I currently used is, using the binary folder comes from msysgit, which should be the find.exe and grep.exe from msys sub system.

At the same time, do not use xargs style for rgrep.

(require 'grep)
(grep-apply-setting
 'grep-find-use-xargs 'exec)

use 'exec style, which you can get more information from grep-find-use-xargs documentation.

The currently problem is, this kind of combination is very slow if you use it to find deep directory tree. However, it at least can use without any problem.
