User-agent: Gnus/5.130004 (Ma Gnus v0.4) Emacs/23.4 (gnu/linux)

Platform: emacs 23.2.1,
          GnuWin32 FindUtils 4.2.20-2
          GnuWin32 Grep-2.5.4

Does anyone know of a way to make the emacs rgrep command work on

I'm trying to run `M-x rgrep RET' on a windows emacs.  I have installed
find and grep from GnuWin32 ( ) and put
them early in the PATH.

When I try to run rgrep it exits with no match, and in the *grep* I see
the following error message:
 C:\ProgramFiles\GnuWin32\bin\find: invalid expression; I was expecting to find 
a ')' somewhere but did not see one.

The command line is:
C:\ProgramFiles\GnuWin32\bin\find . "(" -path "*/SCCS" -o -path "*/RCS" -o 
-path "*/CVS" -o -path "*/MCVS" -o -path "*/.svn" -o -path "*/.git" -o -path

-print0 | xargs -0 -e grep -i -nH -e "searchterm"

Parantheses seems to be balanced...?  I haven't installed xargs, I
think... unless that's part of FindUtils...?
