// .NAME vtkSystemIncludes - transition VTK to ANSI C++, centralize
// inclusion of system files
// .SECTION Description
// The vtkSystemIncludes centralizes the inclusion of system include
// files. (This is particularly important as VTK moves towards ANSI
// C++.)  For example, this include file enables user's to build VTK
// with STL (i.e., use std: :ostream and other standard ANSI C++
// functionality).  A configured flag in vtkConfigure.h
// (VTK_USE_ANSI_STDLIB) must be set to enable ANSI C++ compliance.

// through the C++-style cstdlib or cstring header.  These outer
// headers are included by the streams library in C++-style and
// include blockers are put in place that prevent including the
// C-style versions from ever including the sub-headers.  Therefore we
// have to include the sub-headers here to get the using declarations.
