[boost] Clang 4.0.0 MPL error in Boost next.hpp and prior.hpp

Subject: [boost] Clang 4.0.0 MPL error in Boost next.hpp and prior.hpp

I am trying to check code that works on VS2015 update 3 and GCC 6.3.0 using Clang 4.0.0

I am using the CodeBlocks IDE (though I don't think that is relevant).

The code indirectly uses next.hpp and prior.hpp

There are several warnings like this (after adding the -Wignored-attributes option)
C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\include\immintrin.h|45|warning: __declspec attribute 'intrin_type' is not
supported [-Wignored-attributes]

I:\modular-boost\boost\mpl\next_prior.hpp|44|error: too many arguments provided to function-like macro invocation|

Following suggestions in this thread, I have added -Wno-invalid-token-paste
http://clang-developers.42468.n3.nabble.com/invalid-token-paste-td4025526.html

and also -DBOOST_PP_CONFIG_FLAGS=1,

but I get a blizzard of errors - see below

It would seem that this may be because of a misconfiguration in Boost mpl?

If I understand right, the thread above suggests that this is MS pre-processor-specific MPL code because of code in
boost/preprocessor/config/config.hpp that determines the MPL code?

Is this correct?
Target: x86_64-pc-windows-msvc
-triple x86_64-pc-windows-msvc19.0.24123

Complete log attached in case this helps.

Can anyone say what I am doing wrong and/or suggest a workaround for this?

Thanks

Paul
