What Command Prompt are you running?  You have to use the correct 
"Native Tools" for the target hardware type.  If you are building 
VC-WIN32, then you are targeting 32-bit hardware and need to run the x86 
Native Tools Command Prompt (not the x64 version).  You can't mix and 
match targets.

If you don't want to build it yourself, there are also prebuilt binaries 
and libraries.
