--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Libc++ avoids the problem by adding the additional overloads to the global
namespace in the C++ versions of <math.h> and <stdlib.h>, then having the
<cxxx> headers include the <xxx.h> headers.
We do it the other way around, so that the original libc function is in the
global namespace, and the additional overloads are in namespace std, and that
difference is the root cause.
