  12 # information in Go syntax.
  13
  14 # We currently #include all the files at once, which works, but leads
  15 # to exposing some names which ideally should not be exposed, as they
  16 # match grep patterns.  E.g., WCHAR_MIN gets exposed because it starts
  17 # with W, like the wait flags.
