KWSys provides a platform-independent API to many common system features that are implemented differently on every platform. This library is intended to be shared among many projects, so it has a configurable namespace. Each project should configure KWSys to use a namespace unique to itself. See comments in CMakeLists.txt for details. You are probably reading this file in the source tree of a surrounding project. In that case, see "../README.kwsys" for details of using KWSys in your project.

Commit "Optimize KWSys SystemTools::FileExists on Windows" accidentally added "#undef _WIN32" when including <windows.h> on cygwin, which breaks builds using the -mwin32 flag. This commit removes that line and fixes the real error it was intended to avoid.
