x64 msbuild fails to include stl

On our build system when we build 64 bit builds, the build is failing to find the stl libraries when they are included without the .h.

So if I do #include <string>it fails, but if I do #include <string.h> it works. This fails on the commandline with both msbuild and vcbuild, but works fine if I build in visual studio.

I am making sure that I am running from the correct environment by first calling:

"c:\Program Files (x86)\Microsoft Visual Studio 8\VC\vcvarsall.bat" amd64

This seems to be properly setting the environment and %INCLUDE% is defined as:

C:\Program Files (x86)\Microsoft Visual Studio 8\VC\ATLMFC\INCLUDE;C:\Program Files (x86)\Microsoft Visual Studio 8\VC\INCLUDE;C:\Program Files (x86)\Microsoft Visual Studio 8\VC\PlatformSDK\include;C:\Program Files (x86)\Microsoft Visual Studio 8\SDK\v2.0\include;C:\Program Files (x86)\Microsoft Visual Studio 8\VC\ATLMFC\INCLUDE;C:\Program Files (x86)\Microsoft Visual Studio 8\VC\INCLUDE;C:\Program Files (x86)\Microsoft Visual Studio 开发者_开发百科8\VC\PlatformSDK\include;C:\Program Files (x86)\Microsoft Visual Studio 8\SDK\v2.0\include;C:\Program Files (x86)\Microsoft Visual Studio 8\VC\ATLMFC\INCLUDE;C:\Program Files (x86)\Microsoft Visual Studio 8\VC\INCLUDE;C:\Program Files (x86)\Microsoft Visual Studio 8\VC\PlatformSDK\include;C:\Program Files (x86)\Microsoft Visual Studio 8\SDK\v2.0\include;C:\Program Files (x86)\Microsoft Visual Studio 8\VC\ATLMFC\INCLUDE;C:\Program Files (x86)\Microsoft Visual Studio 8\VC\INCLUDE;C:\Program Files (x86)\Microsoft Visual Studio 8\VC\PlatformSDK\include;C:\Program Files (x86)\Microsoft Visual Studio 8\SDK\v2.0\include;C:\Program Files (x86)\Microsoft Visual Studio 8\VC\ATLMFC\INCLUDE;C:\Program Files (x86)\Microsoft Visual Studio 8\VC\INCLUDE;C:\Program Files (x86)\Microsoft Visual Studio 8\VC\PlatformSDK\include;C:\Program Files (x86)\Microsoft Visual Studio 8\SDK\v2.0\include;

The errors are like this:

c:\dev\msvc80_64\source\myclass.h(3): fatal error C1083: Cannot open include file: 'string': No such file or directory
