I suggest to fix PATH outside Emacs instead.  I wrote in bug#7793 why.

Which find/xargs/grep are these -- Cygwin's or GnuWin32's?

Also, you said just a couple of messages ago, that rgrep did work for
you in "emacs -q".  So is the only difference between that and this
whatever you have on your .emacs?  Or am I missing something else?

There's something else I don't understand.  The style of shell quoting
you show, viz.

  find . \( -path  -o -path \*/attic -o -path \*/junk -o -path \*/SCCS
  -o -path \*/RCS -o -path \*/CVS -o -path \*/MCVS -o -path \*/.svn -o
  -path \*/.git -o -path \*/.hg -o -path \*/.bzr -o -path \*/_MTN -o

is different from what I see on my Windows box:

  find . "(" -path  -o -path "*/attic" -o -path "*/junk" -o -path "*/SCCS"
  -o -path "*/RCS" -o -path "*/CVS" -o -path "*/MCVS" -o -path "*/.svn" -o
  -path "*/.git" -o -path "*/.hg" -o -path "*/.bzr" -o -path "*/_MTN" -o

That is, Emacs is supposed to use double quotes on Windows, because
Windows programs (except Cygwin) don't understand quoting with a
backslash.  Do you see the former style of quoting in "emacs -Q" as
well?
