Since my comment about this setup being dog slow went unnoticed I'd like to reiterate find+xargs+grep are really slow on Windows on just moderately large projects, so I'm looking for a solution to this? Is it switching to ack?

Maybe somebody will post an example config for recent Emacs/ack versions?

Cheers,
Ev

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")

You will be much better off, including with other ports of GNU/Unix
software, if you just put them all on PATH.  I see no good reason for
keeping them in a directory that is not on PATH.  Not every program
called by Emacs has a user option that allows you to spell out its
full absolute file name.

(FWIW, I have a single `bin' directory into which I put _all_ the
programs and DLLs that do not come with Windows out of the box, and
that directory is very near the beginning of PATH.  I have yet to see
a single use case where this arrangement failed me, be it in Emacs or
elsewhere.  So this is what I recommend to others, unless there are
_very_ good reasons not to use this setup.)
