-// This file is needed for windows -- unittests are not part of the
-// gflags dll, but still want to include config.h just like the
-// dll does, so they can use internal tools and APIs for testing.
-//
-// The problem is that config.h declares GFLAGS_DLL_DECL to be
-// for exporting symbols, but the unittest needs to *import* symbols
-// (since it's not the dll).
-//
-// The solution is to have this file, which is just like config.h but
-// sets GFLAGS_DLL_DECL to do a dllimport instead of a dllexport.
-//
-// The reason we need this extra GFLAGS_DLL_DECL_FOR_UNITTESTS
-// variable is in case people want to set GFLAGS_DLL_DECL explicitly
-// to something other than __declspec(dllexport).  In that case, they
-// may want to use something other than __declspec(dllimport) for the
-// unittest case.  For that, we allow folks to define both
-// GFLAGS_DLL_DECL and GFLAGS_DLL_DECL_FOR_UNITTESTS explicitly.
-//
-// NOTE: This file is equivalent to config.h on non-windows systems,
-// which never defined GFLAGS_DLL_DECL_FOR_UNITTESTS and always
-// define GFLAGS_DLL_DECL to the empty string.
