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



------- Comment #2 from pcarlini at suse dot de  2008-02-07 12:07 -------
Just wanted to add that we are also providing a <tr1/cmath>, conforming to the
TR1 specifications, which indeed makes available std::tr1::log2, and also, in
the forthcoming 4.3.0, std::log2, as part of <cmath>, enabled in the
experimental C++0x mode, -std=c++0x: in fact the next C++0x standard will know
about all the C99 math functions.
