   7 // supports, which depends on the what was chosen at configure-time.  For
   8 // example, if Valgrind is installed on an AMD64 machine but has been
   9 // configured with --enable-only32bit then this program will match "x86" but
  10 // not "amd64".

  13 // - 0 if the machine matches the asked-for arch
  14 // - 1 if it doesn't match but does match the name of another arch

  16 // - 3 if there was a usage error (it also prints an error message)

  19 // 'all_archs' as well as adding go().
