It seems that applying patch #6 is equivalent to stop at patch #5, i.e.
we can avoid to change .../texk/web2c/configure.

In any case, the result is that xetex.exe depend on a few Cygwin dlls:

$ cygcheck texlive-20080930-source/inst/bin/i386-cygwin/xetex.exe
texlive-20080930-source/inst/bin/i386-cygwin/xetex.exe
   C:\cygwin\bin\cygwin1.dll
     C:\WINDOWS\system32\ADVAPI32.DLL
       C:\WINDOWS\system32\KERNEL32.dll
         C:\WINDOWS\system32\ntdll.dll
       C:\WINDOWS\system32\RPCRT4.dll
         C:\WINDOWS\system32\Secur32.dll
   C:\cygwin\bin\cygfontconfig-1.dll
     C:\cygwin\bin\cygexpat-0.dll
     C:\cygwin\bin\cygfreetype-6.dll
       C:\cygwin\bin\cygz.dll

Instead applying this:

makes xetex.exe depend only on cygwin1.dll:

$ cygcheck /usr/local/texlive/2008/bin/i386-cygwin/xetex.exe
