+// This header defines __device__ overloads of std::min/max.
+//
+// Ideally we'd declare these functions only if we're <= C++11.  In C++14,
+// these functions are constexpr, and so are implicitly __host__ __device__.
+//
+// However, the compiler being in C++14 mode does not imply that the standard
+// library supports C++14.  There is no macro we can test to check that the
+// stdlib has constexpr std::min/max.  Thus we have to unconditionally define
+// our device overloads.
+//
+// A host+device function cannot be overloaded, and a constexpr function
+// implicitly become host device if there's no explicitly host or device
+// overload preceding it.  So the simple thing to do would be to declare our
+// device min/max overloads, and then #include_next <algorithm>.  This way our
+// device overloads would come first, and so if we have a C++14 stdlib, its
+// min/max won't become host+device and conflict with our device overloads.
+//
+// But that also doesn't work.  libstdc++ is evil and declares std::min/max in
+// an internal header that is included *before* <algorithm>.  Thus by the time
+// we're inside of this file, std::min/max may already have been declared, and
+// thus we can't prevent them from becoming host+device if they're constexpr.
+//
+// Therefore we perpetrate the following hack: We mark our __device__ overloads
+// with __attribute__((enable_if(true, ""))).  This causes the signature of the
+// function to change without changing anything else about it.  (Except that
+// overload resolution will prefer it over the __host__ __device__ version
+// rather than considering them equally good).
+
+#include_next <algorithm>
+
+// We need to define these overloads in exactly the namespace our standard
+// library uses (including the right inline namespace), otherwise they won't be
+// picked up by other functions in the standard library (e.g. functions in
+// <complex>).  Thus the ugliness below.
