Can I build x64 app on a 32 bit machine?

Question

How do I develop a 64bit app on a 32 bit PC?

I'm using VS 2008 on WinXP 32 bit. I set the visual studio linker to /machine:x64 and created x64 configurations. All will compile and link OK, but when I run the dependency walker on the exe I see the 64 bit mscvr90.dll, etc. pointing to all the Win32 dlls, Kernel32.dll, Advapi32, Comdlg32, Gdi32, etc.

When I copy the exe over to run on a Win64 system it is rejected "...application configuration is incorrect". How do I tell visual studio to stay away from the 32 bit realm?

Yes, it's called cross-compiling.
