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