9 # This shell script creates the sysinfo.go file which holds types and
10 # constants extracted from the system header files. This relies on a
11 # hook in gcc: the -fdump-go-spec option will generate debugging
12 # information in Go syntax.
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.
