## Python 2.7 and C++17
The Python 2.7 header files use the `register` keyword, which is [reserved and unused from C+17 onwards](https://en.cppreference.com/w/cpp/keyword/register). Compiling a wheel for Python 2.7 with the C++17 standard is still possible to allow usage of `register` using proper flag `-Wno-register` for gcc/clang and `/wd5033` for MSVC.

## manylinux1 and C++14
The default `manylinux1` image (based on CentOS 5) contains a version of GCC and libstdc++ that only supports C++11 and earlier standards. There are however ways to compile wheels with the C++14 standard (and later): https://github.com/pypa/manylinux/issues/118

## macOS and deployment target versions
OS X/macOS allows you to specify a so-called "deployment target" version that will ensure backwards compatibility with older versions of macOS. One way to do this is by setting the `MACOSX_DEPLOYMENT_TARGET` environment variable. If not set, Python will set this variable to the version the Python distribution itself was compiled on (10.6 or 10.9, for the python.org packages), when creating the wheel.

However, to enable modern C++ standards, the deploment target needs to be set high enough (since older OS X/macOS versions did not have the necessary modern C++ standard library).
