// which is guaranteed to work properly only when the application uses the same
// C++ runtime that SYCL library uses.
// The appplications using sycl.dll must be linked with dynamic/release C++ MSVC
// runtime, i.e. be compiled with /MD switch. Similarly, the applications using
// sycld.dll must be linked with dynamic/debug C++ runtime and be compiled with
// /MDd switch.
// Compiler automatically adds /MD or /MDd when -fsycl switch is used.
// The options /MD and /MDd that make the code to use dynamic runtime also
// define the _DLL macro.
