The libstdc++ part of the following patch [fixincludes, v3] Don't define libstdc++-internal macros in Solaris 10+ <math.h> https://gcc.gnu.org/ml/gcc-patches/2016-11/msg00330.html
has remained unreviewed for a week. Bruce already approved the fixincludes part. In the meantime, full testing on mainline has completed and backports to the gcc-5 and gcc-6 branches have also been tested successfully.
