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:
