Commit "KWSys: Fix SystemTools environment memory handling" (2012-04-26) added a _WIN32 case inside !KWSYS_CXX_HAS_ENVIRON_IN_STDLIB_H to dllimport the "environ" global. Howver, KWSYS_CXX_HAS_ENVIRON_IN_STDLIB_H is true on every Windows toolchain we support so the case is never reached. Furthermore, even if it were reached the use of dllimport is incorrect because the toolchain might not be compiling with a dynamic runtime library. Remove the unused incorrect line and supporting conditionals.
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.
