I thought about that. We'd need some machinery that would allow cpp to query what has been declared already. 
Or alternately, always treat them as user-defined in C++ mode and

Yeah, I think that would be best.

OK, this passes x86_64-linux. This is my first rodeo with *.texi.

I just have one flag: -fext-numeric-literals.
It leaves gnu extension suffixes for std=gnu++*, and std=c++98.
I sets the flag off (use suffixes for user-defined literals) for std=c++11+.
