[h-e-w] xargs fails with "grep: Invalid argument"

when issuing `rgrep' on directories with a lot of files and
subdirectories, I get the following error in "*grep*" buffer:

xargs: grep: Invalid argument

I'm using GnuWin32's `find', 'grep' and `xargs'. I've checked that by issuing:

                   (locate-file "find" exec-path exec-suffixes)
                   (locate-file "grep" exec-path exec-suffixes)
                   (locate-file "xargs" exec-path exec-suffixes)

Below are versions of each software involved and full "*grep*" buffer.
Thanks for your help.
