[Bug c++/14172] New: g++ should ignore warnings in STL headers

["tneumann at pi3 dot informatik dot uni-mannheim dot de" <gcc-bugzilla at gcc dot gnu dot org>]

Some warning options trigger warnings in standard C++ headers, rendering -Werror 
unusable. This can be seen with a simple example:

#include <list>
int main()
{
   std::list<int> foo;
}


When compiling with g++ -Weffc++ -Werror foo.cpp a lot of warnings about STL 
classes are emitted. 
While the gcc manual already mentions that -Weffc++ could produce spurious 
warnings, the same problems occurs with -Winline (I can try to produce a minimal 
test case if required). I think the compiler should ignore warnings in these 
files, as the user cannot fix them.
