Now I get something as bad - back to missing the cstddef file.
I honestly have no idea why you have this problem and I do not. Clang finds the VC include directories for me.
PS You didn't say if I really needed the most recent March 2017 VS update?
It's true that I have VS 2017 installed and Clang finds and uses it, but Edward reports in the other message that VS 2015 works for him (when setting -msc-version=1900 as appropriate.)
I've tried adding to user_config.jam
<cxxflags>"-IC:/Program Files (x86)/Microsoft Visual Studio 14.0/VC/include"
The correct way to set the include path is with <include>"C:/Program Files (x86)/Microsoft Visual Studio 14.0/VC/include" although I'm not sure about the quoting. If that doesn't work, you could try double-quoting: <include>"\"C:/Program Files (x86)/Microsoft Visual Studio 14.0/VC/include\""
