+/* NOTE: libio is now exclusively used only by glibc since libstdc++ has its
+   own implementation.  As a result, functions that were implemented for C++
+   (like *sputn) may no longer have C++ semantics.  This is of course only
+   relevant for internal callers of these functions since these functions are
+   not intended for external use otherwise.
