-std=c++0x vs -std=gnu++0x

 Hello,

 commit 437fe5a444411f68d1848c49121394f16f09611b made me notice that we 
actually build with -std=c++0x and not -std=gnu++0x, which I think would make 
more sense and be consistent with the case when we do not build in C++0x 
mode.

 If you look at the gcc manpage for the description of -std, you'll notice 
that the C++ default is gnu++98, and c++98 is switched to also by 
using -ansi. So if we default to c++0x, we pretty much default to the more 
strict -ansi, only in C++0x mode. That should mean that gcc is more strict 
than its default and e.g. some of its extensions are disabled.

 Any objections to switching to gnu++0x ?
