xfree86 starting problem

[brave buzz <brave_buzz at yahoo dot com>]

Hi! I installed the recent version of cygwin and
xfree86 under d:\cygwin_install.
But when I start the bat file for xfree86, I get the
error that "libz.dll not found" although I've included
the path d:\cygwin_install\lib in PATH. I can see the
file libz.dll.a in this dir. 


Here is the error o/p
Path not found - d:\cygwin_install\tmp\.X11-unix\X0
Path not found
Invalid path, not directory,
or directory not empty
Cannot find file 'XWin' (or one of its components).
Check to
ensure the path and filename are correct and that all
required
libraries are available.

Here is a part of the bat file:
@echo off
SET DISPLAY=24.254.17.64:0.0
SET
PATH=.;d:\cygwin_install\bin;d:\cygwin_install\usr\X11R6\bin;d:\cygwin_install\lib;%PATH%

REM SET XFCE_DATA=d:\cygwin_install\usr\X11R6\var;
xfce

rem cleanup after last run
attrib -s d:\cygwin_install\tmp\.X11-unix\X0
del d:\cygwin_install\tmp\.X11-unix\X0
rmdir d:\cygwin_install\tmp\.X11-unix
