Compiling GDB with C++ Compiler

Hi,

I work on cgdb, a gdb front end.

cgdb was always a C project because gdb was.
The goal was to have cgdb port anywhere that gdb could.

Now that gdb is C++, cgdb has moved to C++.
Is there a specific C++ standard that gdb conforms to with g++?
Forrinstance, c++98 or c++11, or is it more of a wild west scenario?
If there is a specific standard, I'll have cgdb follow that standard as well.

Thanks,
Bob Rossi
