// When a compiler uses Thrust as part of its implementation of Standard C++
// algorithms, a cycle of included files may result when Thrust code tries to
// use a standard algorithm.  Having a macro that is defined only when Thrust
// is including an algorithms-related header gives the compiler a chance to
// detect and break the cycle of includes.  (<memory> declares several standard
// algorithms, including all of the uninitialized_* algorithms.  "_ALGORITHMS_"
// in the macro name is meant generically, not as a specific reference to
// the header <algorithms>.)
