================
Comment at: libcxx/trunk/src/random.cpp:29
+#if defined(_LIBCPP_USING_GETENTROPY)
+#include <sys/random.h>
+#elif defined(_LIBCPP_USING_DEV_RANDOM)
----------------
musl only declares `getentropy` in `<unistd.h>` not `<sys/random.h>`. Glibc declares it in both. Should `<unistd.h>` also be included when `_LIBCPP_USING_GETENTROPY` is defined, so it can work more portably?
