I have not attempted to build clang-8.0 under Windows. I ran into too many errors in the past attempting to build clang on Windows, which were ignored when I mentioned it on the clang developers list, to want to keep pursuing another attempt.
It has become clear [following discussions on the cfe-dev mailing list] that vc/msbuild do(es) not scale well [enough] to build Clang/LLVM. The recommended [and what more or less seems to be the only way] is to use the combo Ninja/Cmake/VC. There are some spells [see llvm web-site] you could utter that allows you to bootstrap Clang with VC and then build Clang with the [that] latest Clang. When I run the preprocessor tests using b2 with my toolset clang-7.0
targeting VC++ I get no errors at all, so I really do not know what you are seeing or what you are doing to produce "lots of errors". I am working with the 'develop' branch of Boost Preprocessor.
As far as I read, Edward said there were 2 errors, one of which he thought, could be ignored. degski -- *“If something cannot go on forever, it will stop" - Herbert Stein*
