It seems that the run time for Windows has changed and supports more math     functions than before.  Since LLVM requires at least VS2015, I assume that this is the run time that would be redistributed with programs built with Clang.  Thus, I based this update on the header file `math.h` that accompanies it.

This patch addresses the PR40541.  Unfortunately, I have no access to a  Windows development environment to fully validate it.
