<pre>This is behaving as intended. The libc builts are always allowed to defer to
the libc implementation, regardless of optimization level (although it is true
that some of them we'll always expand when optimizations are enabled). The
implementation is always allowed to assume the existence of a standard C
library (or C++ library for C++ code) with which to link (regardless of what
headers you include in your translation unit). In fact, the compiler will
generate calls to memcpy and similar functions for implementing some structure
copies without there being an explicit references to memcpy in your source code
at all.</pre>
