If you haven't worked it out by now, CB is not a debugger. As a convenience, it provides an interface to the GDB debugger (and possibly to others). If you have questions about GDB features and "intentions", post them on the GDB site. But if you are expecting the CB/GDB combination (particularly on Windows) to be as powerful, full featured and easy to use as Microsoft's debugger, you are going to be very, very disappointed.
However, even the MS debugger cannot watch (as opposed to step through) functions that actually have been inlined. If the MS environment is allowing you to watch those functions, then they haven't been inlined by the MS compiler.
