The following libstdc++ patch [v3] Handle C++11 <math.h> overloads on Solaris 12 https://gcc.gnu.org/ml/gcc-patches/2015-11/msg02075.html
has remained unreviewed for a week. It fixes a Solaris 12 bootstrap failure and is especially important for the gcc-5 branch at this point. With the GCC 5.3 release imminent, it would be a pity to release without this patch, S12 bootstrap broken and all the effort that went into supporting S12 wasted. Thanks.
