-std=c++0x enables lots of things, but if you don't use e.g. variadic
templates or the decltype keyword you shouldn't notice. The only
thing I can think of affecting valid code is changing the meaning of
the 'auto' keyword, which noone sensible uses anyway.
Using -std=c++0x will cause libstdc++ to build in C++0x mode, which last
time I checked was not strictly ABI compatible with libstdc++ not built
in C++0x mode. So if you link with a dynamic libstdc++.so, you may get
in trouble in some complex scenarios.
