Error building legacy code with VS 2005

Trying to build a legacy code in VS2005 and get errors in VC header files.

d:\Compilers\Microsoft Visual Studio 8\VC\include\xutility(2096) : error C2065: '_Sb' : undeclared identifier
    d:\Compilers\Microsoft Visual Studio 8\VC\include\xutility(2176) : see reference to class template instantiation 'std::istreambuf_iterator<_Elem,_Traits>' being compiled

I find the legacy code uses a vector and if I comment out those variables then the code compiles without any errors. I get these errors even if I just include vector header without defining any variable.

All the files in the project are cpp files.

Do I need to add some preprocessor directives or compiler settings to get this working?

You may find that running the pre-process phase on one of the files might show if any macros are being expanded that conflict with vector or _Strbuf. See my post on how to do this:

Compiling a project (VS 2008) with the /p argument (preprocess to a file) doesn't compile

You probably need to remove some conflicting predefined macros. Leading underscores followed by uppercase letters, as in _Sb are reserved for the implementation. If you have that defined as something else, you'll get such errors. It's also possible the errors are because you've defined _Strbuf ot _Got.
