Please do not do that. I had face-to-face meetings this week with Chandler Carruth and others working on Clang for Windows. They are depending on Boost's tests to find bugs in Clang's emulation of Visual C++, and if you work around their bugs it will deprive them of a valuable testing tool.

They should be testing with BOOST_COMPILER_CONFIG set to "boost/config/compiler/visualc.hpp". That way BOOST_MSVC and the appropriate compatibility macros will be set for them, but we can still use BOOST_MSVC to treat Visual C++ differently to clang.

BOOST_MSVC should only be defined for genuine MSVC, not for any pretenders. That's the whole point of this macro.

Errr, that's what I said. I was suggesting that they could test with BOOST_COMPILER_CONFIG set to the Visual C++ header so it will be set in *their* tests. For our use BOOST_MSVC wouldn't be set.

I don't understand. Why would they test a known to be incorrect configuration?
