  12     Unfortunately, when compiling at maximum warning level, the standard
  13     headers themselves may generate warnings -- and really lots of them. So
  14     before including them, this header should be included to temporarily
  15     suppress the warnings and after this the header afterstd.h should be
  16     included to enable them back again.
  17
  18     Note that there are intentionally no inclusion guards in this file, because
  19     it can be included several times.
