MacOS static libs depend on old-style gnu libstdc++Solved

I've downloaded and taken a crack at the Mac static library build of TA. It seems that you build your .a file against the gcc compiler. Apple is generally not adding modern C++ features to the gcc compiler, as they are now mostly using clang -- most of the primary developers for clang now work at Apple.

I would suggest either compiling and linking against the modern llvm libc++ implementation on Apple or linking with both gnu libstdc as well as llvm libc++ and releasing both static libs for TurboActivate. In general, no new code is being developed on gcc at Apple, and I would be surprised if anyone complained.

Enclosed are the beginning of the cavalcade of errors that occur when you attempt to link TurboActivate.a into an Apple project using clang.
