Fix for Bug#36875: Problem was, that there some warnings has been written containing values,

which were determined by the server depending on the os. The solution is to disable warnings in general.
The check of the values only have been done for Linux and Windows. Now, the check has been changed to the check of
ranges (not more concrete values) being near by the expected (set) values.
