ponyc: GCC 6.1 build failure

gcc 6.1.1

For GCC 6 this has been fixed, by making the C++ library install its own version of math.h, which includes cmath, which then includes the real math.h from the C library.

Use `-I` rather than `-isystem` for LLVM include directory Building on Arch Linux, using gcc 6.1.1 and LLVM 3.7.1, fails with the error: /usr/include/c++/6.1.1/cmath:45:23: fatal error: math.h: ... — committed to tmmcguire/ponyc by tmmcguire 8 years ago

It was a close finish, but Arch surpassed in both the speed and the snide-ness of the response. 😉

You call it snide, I call it common sense. If something doesn’t work when you do something dumb, don’t do something dumb.
