/**
    Unfortunately, when compiling at maximum warning level, the standard
    headers themselves may generate warnings -- and really lots of them. So
    before including them, this header should be included to temporarily
    suppress the warnings and after this the header afterstd.h should be
    included to enable them back again.

    Note that there are intentionally no inclusion guards in this file, because
    it can be included several times.
