------- Comment #9 from chris at bubblescope dot net 2010-04-20 18:53 ------- I don't think it's a front-end issue. '#pragma GCC system_header' is specifically designed to stop warnings in headers. However, it stops 'good' warnings as well as 'bad' warnings. 'system_header' could be extended to allow (or disallow) specific warnings, but that seems like quite a major extension.
Romain: -Wsystem-headers will enable warnings in standard library types. However note that you will get some warnings thrown up, which you won't be able to work around. The only real patch I can think of would be to avoid '#pragma GCC system_header' being defined in C++03 mode, in <memory>. That would be a simple patch like the below. The only problem is that this might left some other warnings sneak back in. Something like (untested, sorry).
