As always, the release managers would appreciate it if you download

the candidate of your choice and give building it a try. Please report

both success and failure, and anything else that is noteworthy.

I have built the RC on Mac OS X 10.11 using Apple LLVM version 8.0.0 (clang-800.0.42.1)

successfully while specifying c++03/11/14/1z

I have built the RC on Mac OS X 10.14 using Apple LLVM version 10.0.0 (clang-1000.10.44.4)

successfully while specifying c++03/11/14,

but failed when specifying c++17/2a, because the Python 2.7 headers shipped with Mac OS 10.14 use the "register" keyword:

In file included from /System/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7/Python.h:85:

/System/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7/unicodeobject.h:534:5: error: ISO C++17 does not allow 'register' storage class specifier [-Wregister]

    register PyObject *obj,     /* Object */

    ^~~~~~~~~

I have built the RC on Mac OS X 10.14 using a recent trunk build of clang (version 9.0.0 (https://github.com/llvm/llvm-project.git 881e83d8b94f1997de674ed8ff382a73a29a719d))

successfully while specifying c++03/11/14,

but failed when specifying c++17/2a, because the Python 2.7 headers shipped with Mac OS 10.13 use the "register" keyword:

In file included from /System/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7/Python.h:85:

/System/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7/unicodeobject.h:534:5: error: ISO C++17 does not allow 'register' storage class specifier [-Wregister]

    register PyObject *obj,     /* Object */

    ^~~~~~~~~

(same results as with Apple's clang)

I have built the RC on Ubuntu 18.14 with gcc 7.3.2

successfully while specifying c++03/11/14,

but failed when specifying c++17/2a, because the Python 2.7 headers shipped with 18.04 use the "register" keyword:

In file included from /usr/include/python2.7/Python.h:88:

/usr/include/python2.7/unicodeobject.h:534:5: warning: 'register' storage class specifier is deprecated and incompatible with C++17 [-Wdeprecated-register]

    register PyObject *obj,     /* Object */

    ^~~~~~~~~

and I had the same results with a recently built version of clang on Ubuntu (success on 03/11/14, but python failures with 17/2a)
