Hi, when report some gdb bug, the developer give us such suggestion. Comment 4 (http://sourceware.org/bugzilla/show_bug.cgi?id=15205#c4).
If the GDB's annotation feature was removed, then we can't use GDB CLI under C::B. Note: the annotation feature was originally used for Emace.
Why are you surprised?
The CLI is made for humans not IDEs.
We will eventually switch to MI, but I have to finish some other tasks before I get to the plugin.
