// 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.
