[Bug libstdc++/35104] New: cmath do not undef log2

[ppershing at gmail dot com]

I found this bug in cygwin's gcc, but it is probably
general problem.
#include <cmath> fails to undefine math.h's macro log2.
I personally thinks, that like other math functions,
log2 shoud be function in namespace std, not macro.
(Bug found, when I was defining own int log2(int) function
 in class)
