#   Build matrix is a Total Mess! Exclude seems to have no action at all. All the
#   logic of 'include' and 'exclude' is unpredictable.
#
#   OSX 'xcode10.2' packages Apple Clang 9.0 based on LLVM 7.0 and doesn't support
#   <filesystem> at ALL (not even experimental)
#
#   LLVM Clang 8.0 screws RocksDB on deprecations and doesn't support <filesystem>
#
#   Wait until LLVM 9.0 which should be ready by the end of this year with 
#   <filesystem> support
#
