Re: [boost] [clang][preprocessor] Testing of clang emualting the VC++ preprocessor on Windows

At best you could hope that particular developers interested in MSVC and Windows would be eager enough to report bugs to MS, but that is unlikely to be the case for every Boost developer.

That's exactly what happened when Microsoft decided to make their compiler conform to the standard, starting with version 7.1. They gave us a direct channel to report bugs in the prerelease 7.1 compiler, which we did. We also introduced BOOST_WORKAROUND to make it easier for compiler vendors to test their new compilers on Boost without workarounds. The preprocessor quirks however are a bit different story, as fixing them will probably break an ungodly amount of code.
