How to cross compile Wireshark x64 on an x86 Windows machine

I am using rev 37663 of Wireshark (1.7.0) and VS 2008 on Windows XP x86 and I would like to compile a 64-bit version of Wireshark. I have followed all the instructions detailed in http://wiki.wireshark.org/Development/Win64

Here's what I've done:

• prepared cmd.exe by running:

  "C:\Program Files\Microsoft Visual Studio 9.0\VC\vcvarsall.bat" x86_amd64

• I've also tried running this command as well, with the same result:
  

  "C:\Program Files\Microsoft Visual Studio 9.0\VC\bin\x86_amd64\vcvarsx86_amd64.bat"

• I've downloaded vcredist_x64.exe and put it into:
  

  C:\wireshark-win64-libs

• I've modified a line in config.nmake to this:
  

  WIRESHARK_TARGET_PLATFORM=win64

I've run the following commands:

nmake -f Makefile.nmake verify_tools
nmake -f Makefile.nmake setup
nmake -f Makefile.nmake distclean
nmake -f Makefile.nmake all

which all succeed until the last command. Here is the output of the last command:
