+// This file is needed for windows -- unittests are not part of the
+// perftools 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 PERFTOOLS_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 PERFTOOLS_DLL_DECL to do a dllimport instead of a dllexport.
+//
+// The reason we need this extra PERFTOOLS_DLL_DECL_FOR_UNITTESTS
+// variable is in case people want to set PERFTOOLS_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
+// PERFTOOLS_DLL_DECL and PERFTOOLS_DLL_DECL_FOR_UNITTESTS explicitly.
+//
+// NOTE: This file is equivalent to config.h on non-windows systems,
+// which never defined PERFTOOLS_DLL_DECL_FOR_UNITTESTS and always
+// define PERFTOOLS_DLL_DECL to the empty string.
