I did try an strace experiment... not very helpful I am afraid:

WILLISMA AT toww5462 ~
$ strace -o foo.txt echo.exe ${PATH} > /dev/null; wc foo.txt
    408    4141   40604 foo.txt

WILLISMA AT toww5462 ~
$ strace -o foo.txt echo.exe ${PATH}${PATH} > /dev/null; wc foo.txt
      0       0       0 foo.txt

Yesterday, in pre-rebase versions of cygwin I was able to get ls to hang;
whilst hanging I could see stuff like I described in

http://sources.redhat.com/ml/cygwin/2002-11/msg00371.html

As of the latest rebase, I don't see hangs with ls.exe, I just get the
immediately-return-to-command-line effect.

Other observations:

If I launch cmd.exe as the shell, and manually put c:\cygwin\usr\bin and
c:\cygwin\bin on my path, 

c:\cygwin\bin\ls.exe *               -- works fine; but I wonder if ls is
being passed "*" or a list of args
c:\cygwin\bin\echo.exe *             -- works fine
c:\cygwin\bin\echo.exe %PATH%        -- works fine
c:\cygwin\bin\echo.exe %PATH%%PATH%  -- fails, immediately returns to
command line
