Targeting Windows XP X64 RETAIL

That looks right. It comes from this section of setenv.cmd: 
Echo Targeting Windows XP X64 %DEBUGMSG%
Echo.
Set Lib=%MSSdk%\Lib\AMD64;%MSSdk%\Lib\AMD64\atlmfc;
Set Include=%MSSdk%\Include;%MSSdk%\Include\crt;%MSSdk%\Include\crt\sy
+s;%MSSdk%\Include\mfc;%MSSdk%\Include\atl
Set Path=%MSSdk%\Bin\Win64\x86\AMD64;%MSSdk%\Bin;%MSSdk%\Bin\WinNT;%pa
+th%
Set APPVER=5.02
Set TARGETOS=WINNT
Title Microsoft Platform SDK XP X64-bit IE 6.0 %DEBUGMSG% Build Enviro
+nment
Goto Finish

As you can see, there's more to it than setting just the path - it also sets the Lib and Include environment variables appropriately.
What does the corresponding section of your setenv.cmd contain ?
Is %MSSdk% being set correctly ? It should be the location you installed to. (For me it's C:\_64\Platform_SDK) Just put an "Echo" in front of the "Set Lib ..." command, and you'll see what %MSSdk% is set to when you run setenv.cmd. What does it produce ? Does it match an existing directory ?
Could you put a copy of your setenv.cmd on your scratchpad - or even post it here ?
As it stands, we've really very little to work with.

Cheers,
Rob
