When using the Windows SDK 7.1 Command Prompt, how do I change the build environment without losing the nmake command?

Question

I just installed the Windows 7.1 SDK and launched the SDK Command Prompt. If I type nmake, I am greeted with this message:

Microsoft (R) Program Maintenance Utility Version 10.00.30319.01
Copyright (C) Microsoft Corporation.  All rights reserved.

NMAKE : fatal error U1064: MAKEFILE not found and no target specified
Stop.

This is what I expect. However, I want to target Windows x64, so I type: setenv /x64. Then if I run nmake, I get an error:

'nmake' is not recognized as an internal or external command,
operable program or batch file.

Why am I getting this error? What am I doing wrong? I am using Windows 8 Consumer Preview 32-bit on my machine.

Edit: here is a diff of the PATH environment variable before and after:

It seems Microsoft forgot to place an nmake.exe binary in the x86_amd64 directory (the others all have it). I suggest copying the nmake.exe in the main Bin directory to the ´Bin/x86_amd64` directory.

When using the Windows SDK 7.1 Command Prompt, how do I change the build environment without losing the nmake command?
