bug#7785: rgrep is broken on woe32

[Sam Steingold]

YAY!!!!!
the following solves my problem for now (I don't know what will happen
tomorrow though :-)

(when sds-winnt
  (setq find-program ;(concat sds-gnuwin-home "bin\\find")
        (w32-convert-standard-filename (concat sds-cygwin-home "bin\\find"))
        xargs-program ;(concat sds-gnuwin-home "bin\\xargs")
        (w32-convert-standard-filename (concat sds-cygwin-home "bin\\xargs"))
        grep-program ;(concat sds-gnuwin-home "bin\\grep")
        (w32-convert-standard-filename (concat sds-cygwin-home "bin\\grep"))
        grep-find-use-xargs 'gnu
        grep-use-null-device nil))

please close this bug; I will reopen it if I ever get stuck again :-(

(Eli, thanks a lot for your patience, I will not be trying anything
else for this as long as the above solution works).
