[Please cc me, as I am not on this list.]

When installing the clang8 MacOS binary by
  wget <clang-binaries-tarball-url>
  tar -xf clang*
  cd clang*
  sudo mkdir /usr/local/clang8
  sudo cp -R * /usr/local/clang8
the compiler works on MacOS 10.13, but not on MacOS 10.14, with an error:
  /usr/local/clang/bin/../include/c++/v1/stdio.h:108:15: fatal error: 'stdio.h' file not found
  #include_next <stdio.h>
              ^~~~~~~~~
The distribution does not seem to contain any other file stdio.h.
