Tried emacs 23.4 which was the newest 23.x available. That got me a bit
further:

'"xargs"' is not recognized as an internal or external command,
operable program or batch file.
In my .emacs I had the following:
;; Make rgrep find the find program from GnuWin32
(setq find-program "C:\\ProgramFiles\\GnuWin32\\bin\\find")
So I looked in grep.el (which defines the find-program variable) and
found that it had an xargs-program variable as well. Defined it like
this in .emacs (note that it is necessary to start a new emacs for the
changes to take effect. Just evaluating that setq in the *scratch*
buffer won't work):
;; Make rgrep find the xargs program from GnuWin32
(setq xargs-program "C:\\ProgramFiles\\GnuWin32\\bin\\xargs")
This worked better, but I got a more or less expected error message that
it couldn't find "grep":
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 | "C:\ProgramFiles\GnuWin32\bin\xargs" -0 -e grep -i -nH -e "searchterm"
C:\ProgramFiles\GnuWin32\bin\xargs: grep: No such file or directory
So I added the following to .emacs, and started a fresh emacs 23.4
instance:
;; Make rgrep find the grep program from GnuWin32
(setq grep-program "C:\\ProgramFiles\\GnuWin32\\bin\\grep")
Success!
So in summary:
- Use emacs 23.4
- Install FindUtils and grep from GnuWin32 http://gnuwin32.sourceforge.net/
- Set variables in .emacs to whereever you installed the GnuWin32
binaries:
;; Make rgrep find the GnuWin32 executables it needs
(setq find-program "C:\\ProgramFiles\\GnuWin32\\bin\\find")
(setq xargs-program "C:\\ProgramFiles\\GnuWin32\\bin\\xargs")
(setq grep-program "C:\\ProgramFiles\\GnuWin32\\bin\\grep")
(The use "C:\ProgramFiles" for the GnuWin32 location, is just an old
habit of mine, to give ported unix programs an installation path with no
spaces)
