This is an interesting one:
------------------------
enum EE {ee};
struct D {
enum EE : 8;
};
------------------------
In C++98, this looks like an unnamed bit field as part of struct D, but
with C++0x we apparently parse this as the beginning of an enum
scoped declaration:
g/x> /home/bangerth/bin/x86/gcc-mainline/bin/c++ -c x.cc
x.cc:3:14: warning: scoped enums only available with -std=c++0x or -std=gnu++0x
x.cc:3:19: error: expected type-specifier before numeric constant
x.cc:3:19: error: expected '{' before numeric constant
x.cc:3:19: error: expected class-key before numeric constant
x.cc:3:19: error: expected unqualified-id before numeric constant
This is a regression.
