If this is VC 6.0, the understand that it comes with 2 C++ libraries, an old
legacy library and one that is close to the ISO C++ standard. Use the old if
you have large amounts of legacy code to support. Otherwise prefer the new.
_DO NOT_ mix the C++ header files.

You are using the old legacy C++ library. Non-standard headers

You are using the new C++ library. Standard headers.
