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.
